Low-fat or low-carb? Are low-fat diets or low-carb diets more effective for weight loss? A sample of 75 subjects went on a low-carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 4.7 kilograms with a sample standard deviation of 7 kilograms. A second sample of 77 subjects went on a low-fat diet. Their sample mean weight loss was 2.5 kilograms with a standard deviation of 6.1 kilograms. Construct a 98% confidence interval for the difference in mean weight loss between the low-carb and low-fat diets. Let M, denote the mean weight loss for low-carb diet. Use the TI-84 calculator and round the answers to one decimal place. A 98% confidence interval for the difference in mean weight loss between the low-carb and low-fat diets is ___
