Question
Looking at this output in the photo, we know that the proportion of the variation in mileage is accounted for by the linear relationship with the weight of the car is 43.8 % and that the estimate of the regression standard deviationis is 6.78.
Determine the equation of the Least Squares Regression Line and what the interpretation of the slope for weight of car is? Then performing a T-test, determine what the value of the t stastitic is if we wanted to test if there is a significant straight-line relationship between the weight and the mileage of a car.
