Is a weight loss program based on exercise just as effective as a program based on diet? The 54 overweight people put on a strict one year exercise program lost an average of 35 pounds with a standard deviation of 9 pounds. The 41 overweight people put on a strict one year diet lost an average of 29 pounds with a standard deviation of 10 pounds. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use t-test for the difference between two independent population means b. The null and alternative hypotheses would be: Ho: μ1 μ2 (please enter a decimal)
