Which are the better statistics to use to compare the penguin heights?
Penguin Heights at Cityview Zoo
(in cm)
Penguin Heights at Park Zoo
(in cm)
OO
оооо
35 36 37 38 39 40 41 42 43 44 45
35 36 37 38 39 40 41 42 43 44 45
O A. Median and standard deviation
O B. Mean and standard deviation
C. Median and IQR
OD. Mean and IQR
SUB
Answer:
The correct options are A and B.
Step-by-step explanation:
The Penguin Heights at City view Zoo (in cm) is:
S = {35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45}
Compute the mean and median of the data:
[tex]\text{Mean}=\frac{1}{n}\sum X\\\\=\frac{1}{11}\times [35+36+37+38+39+40+41+42+43+44+45]\\\\=40[/tex]
[tex]\text{Median}=[\frac{n+1}{2}]^{th}obs.\\\\=[\frac{11+1}{2}]^{th}obs.\\\\=6^{th}obs.\\\\=40[/tex]
The mean and median are same.
Tis implies that the height of penguins are normally distributed.
So, either the mean or median could be the best measure of center.
Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the absolute variability of the distribution of values.
The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.
Thus, the correct options are A and B.

Barb is a freshman attending a 4-year college. She has been approved for a $12000
subsidized federal loan at 4.29% for 10 years. How much will the U.S. Department of
Education pick up in interest costs during her 4.5-year non-payment period?
Answer:
The amount in interest accruable to the U.S. Department of Education after 4.5 years is $2,882.33
Step-by-step explanation:
The given parameters are;
The amount, P of subsidized federal loan Barb has been approved for = $12,000
The interest rate at which the loan was approved, r = 4.29%
The duration of the loan = 10 years
The interest after 4.5 years is given as follows;
[tex]A = P \times \left (1 + \dfrac{r}{n} \right ) ^{n \cdot t}[/tex]
Where;
A = The total amount of the loan plus interest after a given time period
n = The number of compounding of the interest per annum
Plugging in the values, we get;
[tex]A = 12,000 \times \left (1 + 0.049 \right ) ^{4.5} \approx 14,882.33[/tex]
The interest, i, is therefore given as follows;
i = A - P = 14,882.33 - 12,000 = 2,882.33
The interest, i after 4.5 years = $2,882.33
The amount in interest accruable to the U.S. Department of Education after 4.5 years = $2,882.33.
