Expert Solution
Solution :
We can do the regression analysis to find the cholesterol level in 33-years old person. Here dependent variable is Cholesterol level and the independent variable is age.
Regression is performed in excel sheet and result is given there
Equation is
Y = intercept + X * Age
Cholesterol level = 112.35 + 1.735 * Age

A new drug to treat high cholesterol is being tested by
pharmaceutical company. The cholesterol levels for 32 patients were
recorded before administering the drug and after. The average
difference in cholesterol levels (after - before) was 1.8 mg/dL
with a standard deviation of 7.97 mg/dL. Using this information,
the calculated 99% confidence paired-t interval is (-2.066, 5.666).
Which of the following is the best interpretation of this
interval?

PART I
A pharmaceutical company is testing a new drug to increase
memorization ability. It takes a sample of individuals and splits
them randomly into two groups. After the drug regimen is completed,
all members of the study are given a test for memorization ability
with higher scores representing a better ability to memorize. Those
21 participants on the drug had an average test score of 27.501 (SD
= 4.089), while those 21 participants not on the drug had an...
