Extracted text: Is a weight loss program based on exercise more effective than a program based on diet? The 44 overwelght people put on a strict one year exercise program lost an average of 30 pounds with a standard devilation of 10 pounds. The 50 overweight people put on a strict one year diet lost an average of 25 pounds with a standard deviation of 9 pounds. What can be concluded at the a = 0.01 level of signtficance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answerv Select an answerv Select an answerv (please enter a decimal) H: Select an answerv Select an answerv Select an answerv (Please enter a decimal) C. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?v a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that... O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude that the population mean weight loss on the exercise program is more than the population mean weight loss on the diet. O The results are statistically insignificant at a = 0.01, so there is statistically significant evidence to conclude that the population mean weight loss on the exercise program is equal to the population mean weight loss on the diet. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the mean weight loss for the 44 participants on the exercise program is more than the mean weight loss for the 50 participants on the diet. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the population mean weight loss on the exercise program is more than the population mean weight loss on the diet. h. Interpret the p-value in the context of the study. O If the sample mean weight loss for the 44 participants on the exercise program is the same as the sample mean weight loss for the 50 participants on the diet and 1if another 44 participants on the exercise program and 50 participants on the diet are weighed then there would be a 0.65% chance of concluding that the mean weight loss for the 44 participants on the exercise program is at least 5 pounds more than the mean weight loss for the 50 participants on the diet
