According to a study published in the New England Journal of Medicine, overweight people on low-carbohydrate and Mediterranean diets lost more weight and got greater cardiovascular benefits than people on a conventional low-fat diet (The Boston Globe, July 17, 2008). A nutritionist wishes to verify these results and documents the weight loss (in pounds) of 30 dieters on the low-carbohydrate and Mediterranean diets and 30 dieters on the low-fat diet. Let Low-carb or Mediterranean and Low-fat diets represent populations 1...

Suppose you take two random samples of dieters to show that those on a Low-Carb Diet lose more weight than those on a Low-Fat Diet. Use the following table to test the hypothesis H0: µ1 ≤ µ2 versus H1: µ1 > µ2 at 0.05 level of significance (Assume that the population variances are equal but unknown). What is the pooled-variance? weight loss(in pounds) low carb diet group 1, low fat diet group 2 mean 9.70    8.30 variance 3.55   ...

A researcher studied how two diets compare in terms of weight loss after 6 months.       40 people used the first diet. Their sample mean was 44, and their sample standard deviation was 10.        60 people used the first diet. Their sample mean was 37, and their sample standard deviation was 15.       Give the 92% confidence interval for the true difference between the mean weight losses. Can we conclude that the two diets really differ in terms of...

In a recent medical study, 81 subjects were placed on a low-fat diet. After 12 months, their sample mean weight loss was 2.2 kilograms, with a sample standard deviation of 6.1 kilograms. Construct an appropriate test to conclude if the mean weight loss is greater than 0 at an α = 0.01 significance level.
