Using the data in the StudentSurvey dataset, we use technology to find that a regression line to predict weight (in pounds) from height (in inches) is

(a) What weight does the line predict for a person who is 5 feet tall (60 inches)? What weight is predicted for someone 6 feet tall (72 inches)?
(b) What is the slope of the line? Interpret it in context.
(c) What is the intercept of the line? If it is reasonable to do so, interpret it in context. If it is no  reasonable, explain why not.
(d) What weight does the regression line predict for a baby who is 20 inches long? Why is it not appropriate to use the regression line in this case?
