12.59 Hockey G.W. Marino investigated the variables related to a hockey player's ability to make a fast start from a stopped position.13 In the experi- ment, each skater started from a stopped position and attempted to move as rapidly as possible over a 6-metre distance. The correlation coefficient r between a skater's stride rate (number of strides per second) and the length of time to cover the 6-metre distance for the sample of 69 skaters was -0.37.

a. Do the data provide sufficient evidence to indicate a correlation between stride rate and time to cover the distance? Test using = 0.05.

b. Find the approximate p-value for the test.

c. What are the practical implications of the test in part a?
