1. I plan an experiment to test the latest conflicting diet programs. The factor for Diet will involve three different levels: low fat, low carbohydrate, and low calorie. The other factor will involve planned exercise. One level will be coached aerobics and the other will be normal activity. We hope to find out which regime is best at reducing weight. The degrees of freedom for the model are

A. 6.
B. 2.
C. 5.

2. I plan an experiment to test the latest conflicting diet programs. The factor for Diet will involve three different levels: low fat, low carbohydrate, and low calorie. The other factor will involve planned exercise. One level will be coached aerobics and the other will be normal activity. We will have 25 subjects assigned to each treatment combination. We hope to find out which regime is best at reducing weight. The degrees of freedom for error are

A. 149.
B. 144.
C. 5.

3. An experiment tests the effects of new devices to help stop smoking. They tested hypnosis, nicotine gum, nicotine patch, and nicotine inhaler. They believed the effects may differ for men and women, so men and women were randomized to the treatments separately. 25 subjects are randomized into each treatment combination. They obtained the following results
