Low-fat or low-carb? Are low-fat diets more effective for weight loss? A sample of 40 subjects went on a low-carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 2.4 kilograms with a sample standard deviation of 3.72 kilograms. A second sample of 43 subjects went on a low-fat diet. Their sample mean weight loss was 1.4 kilograms with a Ed standard deviation of 3.21 kilograms. Can you conclude that the mean weight loss of subjects having low-carb diets is greater than the mean weight loss of subjects having low-fat diets? Let u, denote the mean weight lost on the low-carb diet and J, denote the mean weight lost on the low-fat diet. Use the a = 0.01 level and the P-value method.
