Answer #1

The problem of finding the relationship between weekly hours spent studying (study) and weekly hours spent working (work) cannot be characterized the problem as inferring whether study “causes” work or work “causes” study due to the following reason:

Correlation does not imply causation. Just because we find strong relationship between weekly hours spent studying (study) and weekly hours spent working (work) , we cannot conclude that study “causes” work or work “causes” study.We cannot deduce a cause - and - effect effect relationship between two variables solely on the basis of an observed association between them.Correlation tells us how strongly the pair of variables are linearly related and change together. It does not tell us why and how behind the relationship. Causation says any change in the value of one variable will cause a change in the other variable.

Suppose you work at a well-known economics consulting firm and your manager has asked you to find the relationship between weekly hours spent at the gym by a group of students and observed weekly loss in their weight. Your manager insists on characterizing this research as inferring whether more time in the gym “causes” more weight loss. Do you agree with your manager’s research specification and the use of the term “causes”? Justify your stand.

We study the relation between students' GPA and the number of hours per week spent studying. To this end, we consider the following regression model, GPA = β 0 + β 1 hours+u where GPA is the variable measuring students' GPA, hours is the variable measuring the number of hours studying, and u is the error term. We found the following OLS estimates: β ^ 0 = 2.67 β ^ 1 = 0.601 What is the predicted GPA of a...
