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 weigh each of them. Two weeks and you weigh them again. For each person you compute how much weight they lose over this period. 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 lose...

A medical statistician wants to estimate the average weight loss of those who have been on a new diet plan for 2 weeks. From a random sample of 100 participants in the diet plan, a mean weight change of -2.5 pounds and a standard deviation of 10 pounds are observed. In order to claim that the diet plan is effective, the whole part of the confidence interval for the mean weight change has to be below zero. In other words,...

1. If we increase our food intake, we generally gain weight. Nutrition scientists can calculate the amount of weight gain that would be associated with a given increase in calories. In one study, 16 nonobese adults, aged 25 to 36 years, were fed 1000 calories per day in excess of the calories needed to maintain a stable body weight. The subjects maintained this diet for eight weeks, so they consumed a total of 56,000 extra calories. According to theory, 3500...

A clinical trial is run to assess the effects of different forms of regular exercise on HDL levels in a sample of healthy men between the ages of 18 and 29. Participants in the study were randomly assigned to either one of three exercise groups (Weight training, Aerobic exercise or Yoga) or to a control group in which they were assigned to a regular exercise program. Participants were instructed to follow the program for 8 weeks. Their HDL levels were...

A cohort study is conducted to assess the effectiveness of a 4-week weight-loss intervention program among overweight men. Sixty participants were randomized into two groups. Group 1 worked with a personal trainer to come up with a physical activity regimen that would best fit their lifestyle, while Group 2 worked with a dietician to co-design a diet program to which the men would most likely adhere. Mean BMI was assessed for each group at the end of the 4 weeks....

In a cognitive psychology experiment, the researcher is interested in whether encoding condition has an effect on memory for a list of words. She recruits 16 subjects to participate in the experiment. Each subject comes to the lab twice to be tested in two different encoding conditions and their memory performance scores are listed below. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level...
