We are looking at HIV positive rates among rural Chinese farmers. One of the variables studied
was education level, which was recorded as 'illiterate," "primary," and "secondary." What type of
variable is education level in this example?
Answer:
Categorical data.
Step-by-step explanation:
Variables can be classified as:
Quantitative: If the variable assumes numeric values.
Categorical: If the variable assumes labels.
In this question:
'illiterate," "primary," and "secondary" are labels, which means that in this example, education level is an example of categorical data.
Education level is a type of categorical variable.
StatisticsA categorical variable is a quantity that has been measured on a nominal scale or on an ordinal scale, but whose values do not represent measurable quantities, so cannot be summed up into totals. The values that a categorical variable can take therefore only consist of names, whether or not the names of the categories to which the values belong.

Chelsey put for $450 into an account with a simple interest rate of 2.5% when she withdrew the money she had earned a total of $67.50 in interest how long did she leave the money in the account
Answer:
5.66 years
Step-by-step explanation:
450 x 1.025^(n) = 450 + 67.50
450 x 1.025^(n) = 517.50
1.025^(n) =(517.50 / 450)
1.025^(n) = 1.15
n = ln(1.15) / ln(1.025)
n = 5.66

Determine the ratio of shaded sections to the total number of sections. Write the ratio as a fraction in simplest form and as a decimal. Then explain its meaning.
Answer:
[tex]\frac{3}{8}[/tex] Or 0.375
Step-by-step explanation:
From the picture attached,
A circle is divided into 8 sections.
Out of which 3 sections have been shaded.
So the ratio of the shaded sections to the total number of sections will be,
3 : 8
Therefore, fraction representing the ratio will be = [tex]\frac{3}{8}[/tex]
And the decimal form of the fraction will be = 0.375

Daniel invests £2200 into his bank account.
He receives 5% per year simple interest.
How much will Daniel have after 2 years?
Answer:
I = $ 220.00
Step-by-step explanation:
I = $ 220.00
Equation:
I = Prt
Solve:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2200 × 0.05 × 2 = 220
I = $ 220.00
The simple interest accumulated
on a principal of $ 2,200.00
at a rate of 5% per year
for 2 years is $ 220.00.

Determine whether Mean Value Theorem can be applied. If so, find all values x=c that satisfy the theorem, or explain why not.
Calculus AB AP
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Time taken = 2 hours 18 minutes
18 / 60 = 0.3 hours
Hence, time taken = 2.3 hours
Speed = distance / time
Speed = 26.2 / 11.3 = 11.39 mi/hr
Hence, according to the mean value theorem ;
The range of time taken is (0, 2.3) whereby a certain time, t exist when the runner attains a speed of 11.39
Since initial and final velocity is 0 ;
The runner attains a speed of 11 mi/hr between :
(0, 2.3) and (t, 2.3)
Mr. O. ran the Disney Marathon the AB AP is (0, 2.3) and (t, 2.3).
Given Data: Time taken = 2 hours 18 minutesTime taken =18 / 60
Time taken = 0.3 hours
Hence,
time taken = 2.3 hours
Speed = distance / timeSpeed = 26.2 / 11.3
Speed = 11.39 mi/hr
According to the mean value theorem ;
The range of time taken is (0, 2.3) whereby a certain time, t exist when the runner attains a speed of 11.39 Since initial and final velocity is 0 ;
The runner attains a speed of 11 mi/hr between : (0, 2.3) and (t, 2.3)
Thus, the AB and AP is (0, 2.3) and (t, 2.3)

Information on a packet of seeds claims that 93% of them will germinate. Of the 180 seeds that I planted, only 167 germinated. Compute a 95% two-sided Agresti-Coull CI on the proportion of seeds that germinate. Use as a point estimator p^ the proportion of seeds that germinated during the experiment. Round your answers to two decimal places (e.g. 98.76).
Answer:
The 95% CI on the proportion of seeds that germinate is (0.89, 0.9256).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Of the 180 seeds that I planted, only 167 germinated.
This means that [tex]n = 180, \pi = \frac{167}{180} = 0.9278[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9278 - 1.96\sqrt{\frac{0.9278*0.0722}{180}} = 0.89[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9278 + 1.96\sqrt{\frac{0.9278*0.0722}{180}} = 0.9256[/tex]
The 95% CI on the proportion of seeds that germinate is (0.89, 0.9256).

If there are 125 boxes of prescription bottle labels at the beginning of inventory cycle, and 25 3/4 remain ,how many boxes of labels remain?
Answer:
Rounded to the nearest integer, there are 32 boxes of labels left.
Step-by-step explanation:
Since there are 125 boxes of prescription bottle labels at the beginning of inventory cycle, and 25 3/4 remain, we can determine how many boxes of labels remain through the following mathematical operations:
3/4 = 0.75
100 = 125
25.75 = X
25.75 x 125/100 = X
3218.75 / 100 = X
32.1875 = X
Thus, rounded to the nearest integer, there are 32 boxes of labels left.
