Please explain steps 5. Are low-fat diets more effective for weight loss?

5. Are low-fat diets more effective for weight loss? A sample of 76 subjects went on a low- carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 4.6 kilograms with a sample standard deviation of 7.07 kilograms. A second sample of 78 subjects went on a low-fat diet. Their sample mean weight loss was 2.6 kilograms with a standard deviation of 5.83 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 ,ul denote the mean weight lost on the low-carb diet and ,uz denote the mean weight lost on the low-fat diet. Use the a = 0.10 level and the P-value method. State the appropriate null and alternate hypotheses and type of the test. Compute the test statistic. How many degrees of freedom are there, using the simple method? Compute the P-value. Determine whether to reject H0. State a conclusion. Thmapu'g
