Are low-fat diets or low-carb diets more effective for weight loss? A sample of 77 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 7.16 kilograms. A second sample of 79 subjects went on a low-fat diet. Their sample mean weight loss was 2.6 kilograms with a standard deviation of 5.90 kilograms. Can you conclude that the mean weight loss differs between the two diets? Let μ1 denote the mean weight lost on the low-carb diet and μ2 denote the mean weight lost on the low-fat diet. Use the a=0.01 level and the TI-84 Plus calculato

Question
Are low-fat diets or low-carb diets more effective for weight loss? A sample of
77
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
7.16
kilograms. A second sample of
79
subjects went on a low-fat diet. Their sample mean weight loss was
2.6
kilograms with a standard deviation of
5.90
kilograms. Can you conclude that the mean weight loss differs between the two diets? Let
μ1
denote the mean weight lost on the low-carb diet and
μ2
denote the mean weight lost on the low-fat diet. Use the
a=0.01
level and the TI-84 Plus calculator.
