Wile E. Coyote needs to know how long it will take for the dynamite to explode after lighting the fuse. He determines that fuse length and detonation time are linearly related and calculates the following: Average fuse length (X): 10.1 inches Standard deviation of fuse length (s,): 2.97 inches Average time to detonate (): 14.9 seconds Standard deviation of detonation time (s,): 3.43 seconds Correlation (r): 0.986 a) What is the linear regression equation? b) How long should he expect to wait before the dynamite explodes if the fuse length is 8 inches?
