Since Fundash was built on rougher terrain, the designer of thecourses suspects that the mean completion time of Fundash is greater than the mean completion time of Coolsprint. To test this, she selects 205 Fundashrunners and 260 Coolsprint runners. (Consider these as independent random samples of the Fundash and Coolspring runners.) The 205 Fundash runnerscomplete the course with a mean time of 77.6 minutes and a standard deviation of 8.2 minutes. The 260 individuals complete Coolsprint with a mean time of76.0 minutes and a standard deviation of 7.7 minutes. Assume that the population standard deviations of the completion times can be estimated to be thesample standard deviations, since the samples that are used to compute them are quite large. At the 0.05 level of significance, is there enough evidence tosupport the claim that the mean completion time, u,, of Fundash is greater than the mean completion time, u, of Coolsprint?
