3. Given the regression equation formula, You are trying to predict how long a Truck will take to stop traveling from a given speed. Data on the x = the weight of a pickup truck (23lbs) and y = distance (in feet). the regression line, y = 23 +0.02x . Which of the following statements is a correct interpretation of the value 0.02 in the regression equation?

a. On average, stopping distance goes up 0.02 ft. for each 1 lbs increase in weight.

b. On average, truck weight goes up 0.02 lb. for each additional foot needed to stop

c. Approximately 2% of the variation in the stopping distances can be explained by the linear relationship between stopping distance and truck weight.

d. The correlation coefficient for this data set is 0.02.

e. On average, the stopping distance is 0.02 when the truck weight is 0
