3. It is accepted that the scores on the Calibrated-Sprint Fitness Test were Normally distributed with an average completion time of 52 seconds and a standard deviation of 8 seconds. A sports therapist decides to test whether barefoot runners have the same average completion time as the general population. She designs a randomized experiment and obtains the following summary statistics: n = 32, x = 56 seconds. Is there evidence at the a = 0.01 level to suggest that barefoot runners have a different average completion time from the general population? Your answer should contain: a clear statement of null and alternative hypotheses calculation of a test statistic (including the formula used) a statement and interpretation of the p-value in terms of statistical significance (you do not need to justify how you found the p-value) a conclusion that interprets the p-value in the context of this research problem.
