The average age at which adolescent girls reach their adult height is 16 years. Suppose you have a sample of 27 adolescent girls who are developmentally delayed, and who have an average age at which they reached their adult height of 17.1 years and a sample variance of 36.0 years. You want to test the hypothesis that adolescent girls who are developmentally delayed have a different age at which they reached their adult height than all adolescent girlCalculate the t statistic. To do this, you first need to calculate the estimated standard error. The estimated standard error is SM______ . The t statistic is_________
Answer:
The estimated standard error is SM=1.1547 . The t statistic is 1.4722.
Step-by-step explanation:
We have to esimate the standard error and test statistic for a sample.
The sample has a size n=27.
The sample mean is M=17.7.
As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=√36=6.
The estimated standard error of the mean is computed using the formula:
[tex]s_M=\dfrac{s}{\sqrt{n}}=\dfrac{6}{\sqrt{27}}=1.1547[/tex]
Then, we can calculate the t-statistic as:
[tex]t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{17.7-16}{1.1547}=\dfrac{1.7}{1.1547}=1.4722[/tex]
How do you relate the points made by Professor Degraeve and the use of decision trees as a decision making tool?
In practice, do you feel that organizations focus more on outcomes or decisions?
Suggest at least one idea as to how an organization can make a cultural shift to focusing on the process associated with decision making as opposed to the outcomes.
Answer:
Organizations really focus more on early results, than on thinking carefully about the decisions they must make to achieve accurate and reliable results.
The diagram of the decision tree really helps to analyze all the possible associated variables that can contribute to a good result.
Step-by-step explanation:
We could think of an organization that has children's toys as its final product; At first this organization might think that it is best to make the most popular toys that are promoted by the advertising media, but making a decision diagram and really evaluating what is best at the moment and how this affects demand, it could be induced to look all the variables that could determine to what extent those "toys" to which the media advertise so much are so acceptable in the children's market; we could really be surprised.

Suppose Harvey owns a small business that produces computer motherboards. He previously owned one machine, machine A, that produced these motherboards. In an effort to increase production, he recently purchased a new machine, machine B, that also produces motherboards. Although both machines produce motherboards at the same rate, Harvey suspects that machine A produces fewer defective motherboards than machine B. In order to test this hypothesis, he randomly selects 260 motherboards produced by machine A and 200 motherboards produced by machine B. He observes that 13 of the sampled items from machine A are defective and 14 sampled items from machine B are defective. Harvey plans to use the sample data he collected to test if the frequency of defective items produced by machine A is less than the frequency of defective items produced by machine B.
Select the appropriate test that Harvey should perform to test his hypothesis.
a. two-sample t-test for two means
b. one-sample z-test for a mean
c. one-sample z-test for a proportion
d. matched-pairs t-test
e. two-sample z-test for two proportions
Answer:
e. two-sample z-test for two proportions
Step-by-step explanation:
He has two machines, which have a proportion of defective motherboards. He want to compare this two proportions.
He takes two samples, one for each machine, and calculate the proportion in order to statistically test if there are significant difference between the proportions.
Then, this is a two-sample z-test for two proportions
Jasmine found a wooden jewelry box shaped like a right rectangular prism. What is the volume of the jewelry box?
Answer:
The volume of the jewelry box will be given by,
[tex]\text{Volume}=\text{l}\times \text{w}\times\text{h}[/tex]
Step-by-step explanation:
It is provided that, Jasmine found a wooden jewelry box shaped like a right rectangular prism.
Consider the diagram below for the shape of a right rectangular prism.
The volume of a right rectangular prism is given by the formula:
[tex]\text{Volume}=\text{l}\times \text{w}\times\text{h}[/tex]
Here,
l = length of the rectangle
w = width of the rectangle
h = height of the rectangular prism
Thus, the volume of the jewelry box will be given by,
[tex]\text{Volume}=\text{l}\times \text{w}\times\text{h}[/tex]
Answer:
In the given problem, since it was stated that the dimension of the right rectangular prism is 8 by 6 by 14 cm. To solve the problem, you can use the formula for finding the volume. Therefore, the volume of the jewelry box is 672 cubic cm.
A broth used to manufacture a pharmaceutical product has its sugar content, in mg/mL, measured several times on each of three successive days.
Day 1: 5.0, 4.8, 5.1, 5.1, 4.8, 5.1, 4.8, 4.8, 5.0, 5.2, 4.9, 4.9, 5.0
Day 2: 5.8, 4.7, 4.7, 4.9, 5.1, 4.9, 5.4, 5.3, 5.3, 4.8, 5.7, 5.1, 5.7
Day 3: 6.3, 4.7, 5.1, 5.9, 5.1, 5.9, 4.7, 6.0, 5.3, 4.9, 5.7, 5.3, 5.6
Can you conclude that the variability of the process is greater on the third day than on the second day?
Answer:
Yes
Step-by-step explanation:
To compare the variability of the measured sugar content for each day, we can estimate the standard deviation using the Range rule.
Standard Deviation =[tex]\dfrac{\text{Maximum Value-Minimum Value}}{4}[/tex]
Day 1
5.0, 4.8, 5.1, 5.1, 4.8, 5.1, 4.8, 4.8, 5.0, 5.2, 4.9, 4.9, 5.0
Maximum Value=5.2Minimum Value=4.8Standard Deviation =[tex]\dfrac{5.2-4.8}{4}[/tex]
=0.1
Day 2
5.8, 4.7, 4.7, 4.9, 5.1, 4.9, 5.4, 5.3, 5.3, 4.8, 5.7, 5.1, 5.7
Maximum Value=5.8Minimum Value=4.7Standard Deviation =[tex]\dfrac{5.8-4.7}{4}[/tex]
=0.275
Day 3
6.3, 4.7, 5.1, 5.9, 5.1, 5.9, 4.7, 6.0, 5.3, 4.9, 5.7, 5.3, 5.6
Maximum Value=6.3Minimum Value=4.7Standard Deviation =[tex]\dfrac{6.3-4.7}{4}[/tex]
=0.4
Since the estimated standard deviation of the third day is higher than that of the second day, the variability of the process is greater on the third day than on the second day.
a team won 8 of the 24 games it played in one season .what percentage of the games did it win
Answer:
The team won 33.33% of their games.
Step-by-step explanation:
Proportion and percentage of games won:
The proportion of games won is the number of games won divided by the total number of games.
The percentage of games won is the proportion multiplied by 100.
We have that:
8 wins in 24 games.
So
8/24 = 0.3333
0.3333*100 = 33.33%
The team won 33.33% of their games.

In circle T, m AB = (3x + 9° and mCD = (11x – 71).
What is the measure of AB?
61°
37°
10°
39°
Answer:
D. 39°
Step-by-step explanation:
mAB = (3x + 9°)
mCD = (11x – 71)
From the diagram: |AB|=|CD|
Since arcs AB and CD are subtended by a chord of equal length.
mAB=mCD
3x + 9°=11x – 71°
Collect like terms to solve for x
11x-3x=9°+71°
8x=80°
x=10°
Therefore, the measure of AB:
mAB = (3x + 9°)
=3(10)+9
=30+9
=39°
The correct option is D.
Solve for x in the diagram.
Answer:
x = 20
Step-by-step explanation:
x° + 2x° + (x+10)° = 90°
3x° + x° + 10° = 90°
4x° + 10° = 90°
4x° = 90°-10°
4x° = 80°
x = 80/4
x = 20
Answer:
20°
Step-by-step explanation:
The sum of all three angles combined is 90°. You can see this by the square at the corner. This means that you have to add all of the angles together and set it equal to 90° to solve for x.
x° + 2x° + (x + 10)° = 90°
3x° + (x + 10)° = 90°
4x° + 10° = 90°
4x° = 80°
x = 20°
40% of a number is 44. Find the number
Answer:

Step-by-step explanation:
[tex]V=whl=15*7*6=630ft^3(truck)[/tex]
[tex]V=whl=1.25*2.5*2=6.25ft^2(boxes)[/tex]
To determine how many boxes can go in each truck you have to divide the volumes with ach other so 630/6.25 which equals 100.8
So you could say 2 trucks because each truck can carry 100.8 boxes each
[tex]V=\frac{1}{4} h\sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4} \\V=\frac{1}{4} *7.1*\sqrt{-4^4+2*(4*5)^2+2*(4*4)^2-5^4+2*(5*4)^2-4^4} \\=55.42m^3\\(chalet)[/tex]
There is allowed 1 person per 15m^3 and there are 5 people. Only 3 people can stay in the chalet equalling 45m^3 leaving 10m^3 left thus, not allowing anymore people to stay in the chalet. So the family cant meet the fire safety standards with 5 people
Answer:
9) 630 ft^3; 6.25 ft^3; 2 trucks (3, if you consider space utilization)
10) 71 m^3; 4 persons; no
Step-by-step explanation:
9) The volume of the truck is the product of the dimensions:
V = LWH = (15 ft)(7 ft)(6 ft) = 630 ft^3 . . . truck V
Likewise, the volume of a storage box is the product of its dimensions:
V = LWH = (2 ft)(2.5 ft)(1.25 ft) = 6.25 ft^3 . . . box V
If the boxes pack well into the truck (they don't), then the number of boxes that would fit in the truck is the ratio of these volumes:
number of boxes = (630 ft^3)/(6.25 ft^3) = 100.8
This suggests that half of the 200 boxes will fit in one truck, so 2 trucks are needed.
__
Comment on space utilization
In the real world, not all of the truck's interior space can be utilized. This is because not all of the truck dimensions are integer multiples of the box dimensions. 96 is about the most boxes that can be placed in the truck. (Fitting more than 90 requires boxes be first layered one way, then layered another way to fill as much of the remaining space as possible.) In the real world, 3 trucks are needed to move 200 of these boxes.
___
10) The area of the end triangle of the chalet is ...
A = (1/2)bh = (1/2)(5 m)(7.1 m) = 17.75 m^2
Then the volume of the chalet is ...
V = Bh = (17.75 m^2)(4 m) = 71 m^3 . . . volume of the chalet
At 15 m^3 per person, there is enough volume for ...
(71 m^3)/(15 m^3/person) = 4.73 persons
4 persons can stay in the chalet.
No, the entire family cannot stay in the chalet.
Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200students in group 1 had a mean score of 24.5 with a standard deviation of 4.3, while the 200 students in group 2 had a mean score of 16.3 with a standard deviation of 3.1.Complete parts (a) and (b) below.(a) Determine the 90% confidence interval for the difference in scores, mu 1 minus mu 2.Interpret the interval. ( , ) (Round to three decimal places asneeded.)Interpret the interval. Choose the correct answer below.A.There is a 90% probability that the difference of the means is in the interval.B.The researchers are 90% confident that the difference of the means is in the interval.C.The researchers are 90% confident that the difference between randomly selected individuals will be in the interval.D.There is a 90% probability that the difference between randomly selected individuals will be in the interval.(b) What does this say about priming?A.Since the 90% confidence interval does not contain zero, the results suggest that priming does not have an effect on scores.B.Since the 90% confidence interval does not contain zero, the results suggest that priming does have an effect on scores.C.Since the 90% confidence interval contains zero, the results suggest that priming does have an effect on scores.D.Since the 90% confidence interval contains zero, the results suggest that priming does not have an effect on scores.
Answer:
Step-by-step explanation:
a) The formula for determining the confidence interval for the difference of two population means is expressed as
Confidence interval = (x1 - x2) ± z√(s²/n1 + s2²/n2)
Where
x1 = sample mean of group 1
x2 = sample mean of group 2
s1 = sample standard deviation for data 1
s2 = sample standard deviation for data 2
For a 90% confidence interval, the z score is 1.645
From the information given,
x1 = 24.5
s1 = 4.3
n1 = 200
x2 = 16.3
s2 = 3.1
n2 = 200
x1 - x2 = 24.5 - 16.3 = 8.2
z√(s1²/n1 + s2²/n2) = 1.645√(4.3²/200 + 3.1²/200) = 1.645√0.1405
z = 0.62
Therefore, the 90% confidence interval is 8.2 ± 0.62
Interpretation:
B.The researchers are 90% confident that the difference of the means is in the interval.
b) B.Since the 90% confidence interval does not contain zero, the results suggest that priming does have an effect on scores.

The field was 5⁄6 of an acre and 1⁄3 of the field was planted in strawberries. How many acres are planted in strawberries?
acres
Answer:
333 miliacres
Step-by-step explanation:
First of all, you should know that 1 acre is the same as 4046.9 m²
So, 1/3 of those 4046.9 m² is fully covered by strawberries.
By the way, 4046.9m² . 1/3 = 1348.96 m². This is our planted field.
Let's convert the measure to acres, though:
1348.96 m² . 1 acre / 4046.9 m² = 0.333 acres
0.333 acres . 1000 / 1 acre = 333 miliacres
If you want to know in another unit, let's do another conversion
0.333 acre . 43560 square feet / 1 acre = 14520 square feet

If SinP + SinQ = 7/5 and angle P + angle Q = 90 degrees, without the use of a calculator, determine the value of Sin2P
Answer:
sin2P ≈ 1Step-by-step explanation:
Given SinP + SinQ = 7/5...1 and
∠P + ∠Q = 90°... 2
From compound angle; SinP +SinQ = [tex]2sin(\frac{P+Q}{2} )cos(\frac{P-Q}{2} )[/tex]... 3
Substituting equation 2 into 3 we will have;
SinP +SinQ = [tex]2sin(\frac{90}{2} )cos(\frac{P-Q}{2} )[/tex] = 7/5
[tex]2sin45^{0} cos\frac{P-Q}{2}=7/5[/tex]
since P = 90-Q from equation 1, then;
[tex]2sin45^{0} cos\frac{90-Q-Q}{2}=7/5\\2sin45^{0} cos\frac{90-2Q}{2}=7/5\\2(\frac{1}{\sqrt{2} } ) cos\frac{90-2Q}{2}=7/5\\cos\frac{90-2Q}{2} = 7/5* \frac{\sqrt{2} }{2} \\cos\frac{90-2Q}{2} = \frac{7\sqrt{2}}{10}\\\frac{90-2Q}{2} = cos^{-1} \frac{7\sqrt{2}}{10}\\\frac{90-2Q}{2} = 8.15\\90-2Q = 16.30\\2Q = 90-16.3\\2Q = 73.7\\Q = 36.85^{0} \\\\P = 90-36.85\\P = 53.15^{0}[/tex]
To get sin2P; Accoding to the trig identity;
Sin2P = 2SinPCosP
Sin2P = 2Sin53.15cos53.15
sin2P = 0.9598
sin2P ≈ 1
A coal mine worker is 650 feet below the ground in a mine. Another coal mine worker is 7 feet above ground operating machinery.
Write an integer for the position of each worker relative to the ground.
Find the absolute value of each integer.
Which worker is farther from the ground surface?
Answer:
The first coal mine worker is 650 feet below, so they're -650 ft.
The second coal mine worker is 7 feet above, so they're +7 ft.
| -650 | = 650 ft
| 7 | = 7 ft
650 > 7, so the first worker is farther from the surface.

When a fraction equals zero :
8.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
2•(x-32)
———————— • 8 = 0 • 8
8
Now, on the left hand side, the 8 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
2 • (x-32) = 0
Equations which are never true :
8.2 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
8.3 Solve : x-32 = 0
Add 32 to both sides of the equation :
x = 32
One solution was found :
x = 32
