The Gross Horsepower of a car can influence the mileage of the car. A random sample of 32 different cars’ Gross Horsepower and mileage (Miles/gallon) is collected. From the data, suppose you got the following results:       Pearson’s correlation coefficient: -0.90       The fitted regression line: Ŷ = 30. 10 − 0. 07 X d. Find the value of R2 and comment.  e. From the fitted model find the values of Y for given values of X as 110. How do you interpret this value?
