10.2.3Need help parts B and C please

Is a weight loss program based on exercise less effective than a program based on diet? The 45 overweight people put on a strict one year exercise program lost an average of 25 pounds with a standard deviation of 9 pounds. The 45 overweight people put on a strict one year diet lost an average of 30 pounds with a standard deviation of 6 pounds. What can be concluded at the ax = 0.10 level of significance? a. For this study, we should use [t-test for the difference between two independent population means Ho: 1 O C b. The null and alternative hypotheses would be: H₁: 1 888 c. The test statistic d. The p-value = < p2 u2 Y (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.)
