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

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...
