Can you please help in answering the following questions and put it in Excel:

7.A study is run comparing HDL cholesterol levels between men who exercise regularly and those who do not. The data are shown below.

Regular Exercise	N	Mean	Std Dev
Yes	35	48.5	12.5
No	120	56.9	11.9

Generate a 95% confidence interval for the difference in mean HDL levels between men who exercise regularly and those who do not.

8.For each question below, provide a brief (1-2 sentences) response.

A)How is the slope coefficient (b₁) in a simple linear regression different than the coefficient (b₁) in a multiple linear regression model?

B)When would a survival analysis model be used instead of a logistic regression model?

C)What is the appropriate statistical test to assess whether there is an association between obesity status (normal weight, overweight, obese) and 5-year incident cardiovascular disease (CVD)? Suppose each participants obesity status (category) is known as is whether they develop CVD over the next 5 years or not.
