Fuel economy

Fuel economy. A consumer organization has reported test data for 50 car models. We will examine the association between the weight of the car (in thousands of pounds) and the fuel efficiency (in miles per gallon). Shown are the scatterplot, summary statistics, and regression analysis:

a) Is there strong evidence of an association between the weight of a car and its gas mileage? Write an appropriate hypothesis.

b) Are the assumptions for regression satisfied?

c) Test your hypothesis and state your conclusion.
