Question

Low-fat or low-carb? 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? Use α = 0.01.

Are low-fat diets or low-carb diets more effective for weight
loss? A sample of 46 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 6.28

Find the test statistic for the t test and state the
conclusion. Are low-fat diets or low-carb diets more
effective for weight loss? A sample of 78 subjects went on a
low-carbohydrate diet for six months. At the end of that time, the
sample mean weight loss was 15.0 pounds with a sample standard
deviation of 7.77 pounds. A second sample of 74 subjects went on a
low-fat diet. Their sample mean weight loss was 16.3 with a

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.

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...

Determine the test used for the following problem: Does the
standard deviation in the weight loss of dieters who follow the
low-carb diet differ from the standard deviation of the dieters who
follow the low-fat diet?

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.

The company SlimDown makes weight loss products. It has
recently come out with a new skin cream that, when rubbed behind
the ears, is thought to cause the user to lose weight. To test the
cream, a random sample of 49 people was chosen, and the percentage
weight loss over an eight week period recorded. Find the power of
the test to determine if the the new cream is effective, when the
mean percent weight reduction is actually 1.7%. Assume...
