இ Low-fat or low-carb? Are low-fat diets or low-carb diets more effective for weight loss? A sample of 48 subjects went on a low-
carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 2.9 kilograms with a sample standard
deviation of 4.46 kilograms. A second sample of 46 subjects went on a low-fat diet. Their sample mean weight loss was 1.5
kilograms with a standard deviation of 3.44 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 u, denote the mean weight lost on the low-fat diet. Use the a=0.1 level and the TI-84 Plus calculator.
