A study about the effect of the swing on putting in golf showed a very strong linear relationship between y putting distance and the square of x clubs impact velocity (r2 is in the range 0 985 to 0 999) a For the model y x2, explain why it is sensible to set 0 b If the appropriate model is y x2, explain why if you double the velocity of the swing, you can expect to quadruple the putting distance

Question: A study about the effect of the swing on putting in golf showed a very strong linear relationship between y = putting distance and the

A study about the effect of the swing on putting in golf showed a very strong linear relationship between y = putting distance and the square of x = club’s impact velocity (r2 is in the range 0.985 to 0.999).
a. For the model μy = α + βx2, explain why it is sensible to set α = 0.
b. If the appropriate model is μy = βx2, explain why if you double the velocity of the swing, you can expect to quadruple the putting distance.
