9.7 Hypothesis Test to Compare Two Population Means: Matched-Pair Experiments
A fitness researcher has decided to test the weight loss effects of a sprinting program versus a traditional jogging plan. Each participant engaged in the running programs for 3 months, but some did the jogging first and other did the sprinting first. Use the results below and a 5% significance level to test the claim that the sprinting program produces more weight loss than the jogging.
