Suppose that a random sample of 200 twenty-year-old men is selected from a population and these men’s height (in inches), Hi , and weight (in pounds), Wi , are recorded. OLS estimation of a simple linear regression model relating weight to height yields the fitted regression model:

a) What is the regression’s weight prediction for someone who is 60inches tall?

b) A man has alate growth spurt and grows 2inches over the course of a year.  What is the regression’s prediction for the increase in this man’s weight?
