Another ride The regression of Duration of a roller coaster ride on the height of its initial Drop, described in Exercise 30, had R2 = 15.2%.

a) What is the correlation between Drop and Duration?

 b) What would you predict about the Duration of the ride on a coaster whose initial Drop was 1 standard deviation below the mean Drop?

c) What would you predict about the Duration of the ride on a coaster whose initial Drop was 3 standard deviations above the mean Drop?
