In a study of the effectiveness of a certain diet, 100 subjects went on the diet for a period of six months. The sample mean weight loss was 0.5 pound, with a sample standard deviation of 4 pounds.Can you conclude that the diet produces a mean weight loss that is greater than 0? Use the α = 0.05 level of significance.Perform the hypothesis test, make sure you follow each step and show all your work.

Here we study the effectiveness of two dieting methods. Method 1 is a diet high in protein, fiber, and fat but low in carbohydrates. Method 2 is a diet low in fat but high in fiber and carbohydrates. After one year, a sample of participants from each diet method were checked for the amount of weight lost. The 99% confidence intervals for the mean weight loss of each plan are given below. Method 1:   8.61 < μ < 9.59 Method 2:   6.19...
