Six subjects took part in a weight loss study. Each subject was weighed at the beginning of the study. The subjects then completed a six-week diet and exercise plan. They were weighed after completing the plan.

Subject Weight Before (lbs.) Weight After (lbs.)
1 285 253
2 265 230
3 302 285
4 293 298
5 269 255
6 288 271

The results are shown below The variable Weight Change is defined as the Weight After minus the Weight Before. What is the average weight change? Include 1 decimal place in your answer.

In a test of the Weight Watchers weight loss program, weights of 42 subjects are recorded before and after the program such that the x-value is an individual's weight at the start of the program and the y-value is the same person's weight after one year on the program. The mean of the starting weights was 192.7 pounds. The mean of the weights after one year was 178.2 pounds. The regression equation was found to be yˆ=.802x+30.27ŷ=.802x+30.27.

In a study of the effectiveness of physical exercise in weight reduction, 12 subjects followed a program of physical exercise for two months. Their weights (in pounds) before and after this program are shown in the table. Use Wilcoxon's signed-ranks test and a significance level of 0.05 to test the claim that the exercise program has no effect on weight.

For the clinical trials of a weight-loss drug containing Garcinia Cambogia the subjects were randomly divided into two groups. The first received an inert pill along with an exercise and diet plan, while the second received the test medicine along with the same exercise and diet plan. The patients do not know which group they are in, nor do the fitness and nutrition advisors. a. Which is the treatment group? b. Which is the control group (if there is one)?...

60 observations from a study on the impact of exercise and diet on body weight loss. The variables, exercise, diet, and exdiet are binary variables and the variable diff is a continuous variable. All of these are defined as follows: exercise = 1 if a person exercises, 0 otherwise diet = 1 if a person follows a diet plan, 0 otherwise exdiet = 1 if a person exercises and follows a diet plan, 0 otherwise diff = The difference observed...

A research team conducted a survey in which the subjects were adult smokers. Each subject in a sample of 200 was asked to indicate the extent to which he or she agreed with the statement. “I would like to quit smoking”. The results were as follows. Strongly Agree: 102 Agree: 30 Disagree: 60 Strongly disagree: 8 Can one conclude on the basis of these data that, in the sampled population, opinions are not equally distributed over the four levels of...

A course consists of many subjects, but each subject can only be associated with one course. Each subject is co-ordinated by a lecturer and each lecturer can co-ordinate many subjects. Subjects and courses are identified by subject and course codes, and have a name. Lecturers are identified by an ID and have a name, room number and telephone contact number .a. Using Enterprise Architect, create an ERD representing the above scenario. You need to include the cardinality of the relationships....
