  1. Suppose a new company is interested in promoting their new diet management program. The concept is similar to weight watchers and involves an overall reduction of daily calorie intake. Before making a more direct effort at promoting the success of their program, the company wants to get an idea of how effective their program is based on a SRS. Assume the following table represents results pre and post intervention of 5 individuals varying approximately to a normal distribution.

A) What type of t-test would you use here?

B) Carry out an appropriate t test investigating the effectiveness of the new weight loss intervention at reducing overall calorie intake with alpha=.05. Be sure to include each of the four steps of hypothesis testing. Do not use excel or graphing calculator.

Week 10 Assessment Background Researchers are interested in determining if a new diet program is effective at helping people lose weight. In a pilot study, the researchers collect a random sample of 10 subjects and measure their weight before beginning the diet, then again after one month on the diet program. Data The following table summarizes the information collected: Patient Weight Before (in lb) Weight After (in lb) Difference (After minus Before) Subject #1 207 202 -5 Subject #2 179...

Question 2 Suppose a researcher is interested in the effectiveness in a new childhood exercise program implemented in a SRS of schools across a particular county. In order to test the hypothesis that the new program decreases BMI (Kg/m2), the researcher takes a SRS of children from schools where the program is employed and a SRS from schools that do not employ the program and compares the results. Assume the following table represents the SRSs of students and their BMIs....

Investigators are interested in whether a new diet lowers total cholesterol in a group of individuals. They take a sample of 28 participants on the new diet. They know that the mean cholesterol level of the general population (µ) is 201 mg/dL, but they do not have information on the standard deviation of the population. The mean total cholesterol level in their sample of participants is 195 mg/dL and their sample has a standard deviation of 9 mg/dL. Your research...

Paired Samples t-test (30pts)Suppose you are interested in deciding if a particular diet is effective in changing people’s weight. You decide to run a “within subject” experiment. You select 6 people and weight each of them. Two weeks, you weight them again. For each person, you compute how much weight they lost over this period. This is what you find:Non-diet(subject 1-6): 0,8,3,2,-10,-1.You then put them on the diet and weigh them again after two weeks and compute how much they...

Part II. Researchers are testing the effects of a new diet program on n = 10 healthy participants. One topic that researchers are interested in are overall attitudes towards dieting. They are interested in knowing if the new diet program will change the participants attitudes towards dieting. Participants rated their attitude about diets before and after the diet program.
