Question 6 options:

In a study of n=76 subjects that were placed on a low-fat diet, their sample mean weight loss was 2.2 kg. with a sample standard deviation of 6.1 kg.

What is the test statistic for testing the mean weight loss is GREATER than 0?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38

In a study of n=76 subjects that were placed on a low-fat diet, their sample mean weight loss was 2.2 kg. with a sample standard deviation of 6.1 kg.

What is the P-VALUE of the test if the mean weight loss is GREATER THAN 0?  Use calculator.

Note: Enter X.XXX AT LEAST ONE DIGIT BEFORE THE DECIMAL, THREE AFTERand round up. Thus, 27 is entered as 27.000, 3.5468 is entered as 3.547, 0.3754 is entered as 0.375

In a​ study, 272 moderately obese subjects were randomly assigned to one of three​ diets: low-fat,​ restricted-calorie; Mediterranean,​ restricted-calorie; or​ low-carbohydrate, nonrestricted-calorie. The prediction was that subjects on a​ low-carbohydrate diet would lose​ weight, on the average. After two​ years, the mean weight loss was 5.5 kg for the 109 subjects in the​ low-carbohydrate group with a standard deviation of 7.0 kg.

A health researcher was interested in comparing three methods of weight loss: low-calorie diet, low-fat diet, and high-exercise regimen. He selected 15 moderately overnight subjects and randomly assigned 5 to each weight-loss program. The following weight reductions (in pounds) were observed after a one-month period: Low-fat diet: 7,6,8,8,6 low Calorie diet: 7,7,5,4,5 high exercise: 7,8,7,9,8   a) Test the null hypothesis that the extent of weight reduction does not differ by type of weight-loss program. (Set α=.01 level) (10 points) b)...
