A trainer wanted to see if her new training regimen was effective in reducing the time it took to finish a particular obstacle course. The general public finishes it in 49 seconds with a standard deviation of 12. After testing 64 of her clients, they run the obstacle course in 41 seconds. Was the effective in reducing the time? What are the groups? What are the null and research hypotheses? What are the numbers needed to compute the formula? What is the z statistic? For a one tailed test at .05 significance, the critical value is 1.65. What decision do we make? What is the effect size? (M-μ/σ)
