Low-fat or low-carb? Are low-fat diets or low-carb diets more effective for weight loss? A sample of 93 subjects went on a low- carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 3.1 kilograms with a sample standard deviation of 7.09 kilograms. A second sample of 95 subjects went on a low-fat diet. Their sample mean weight loss was 5.7 kilograms with a standard deviation of 8.65 kilograms. Can you conclude that the mean weight loss of subjects having low-carb diets is less than the mean weight loss of subjects having low-fat diets? Let denote the mean weight lost on the low-carb diet and denote the mean weight lost on the low-fat diet. Use the = 0.1 level and the TI-84 Plus calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. Ho This hypothesis test is a left-tailed Part 2 of 4 test. Compute the P-value. Round the answer to four decimal places. P = 1 Part 3 of 4 Determine whether to reject Ho. Reject the null hypothesis Ho. Part: 3 / 4 Part 4 of 4 State a conclusion. There is enough evidence to conclude that the mean weight loss of subjects having low-carb diets is less than the mean weight loss of subjects having low-fat diets.
