G. W. Marino investigated the variables related to a hockey player's ability to make a fast start from a stopped position.10 In the experiment, each skater started from a stopped position and attempted to move as rapidly as possible over a 6-meter 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-meter distance for the sample of 69 skaters was -.37.
a. Do the data provide sufficient evidence to indicate a correlation between stride rate and time to cover the distance? Test using a = .05.
b. Find the approximate p-value for the test.
c. What are the practical implications of the test in part a?
