A researcher randomly assigned individuals to one of three groups and noted their monthly intake of broccoli (in pounds). At the 0.05 level of significance, can it be concluded that there is a difference in the means?

Group A

2.3 3.1 1.4 2.6 1.8

Group B

1.4 1.9 2.3 1.2

Group C

1.8 3.4 1.1 2.6

?1 = 5	?2 = 4	?3 = 4
̅̅̅ ?1 = 2.24	̅̅̅ ?2 = 1.7	̅̅̅ ?3 = 2.225
?2 = 0.67 1	?2 = 0.50 2	?2 = 0.99 3

Depressed patients were randomly assigned to one of three groups: a placebo group, a group that received a moderate dose of the drug, and a group that received a high dose of the drug. After four weeks of treatment, the patients completed the Beck Depression Inventory. The higher the score, the more depressed the patient. We are now also interested if a patient's weight has an effect on the drug's effectiveness. Patients were categorized as either underweight, overweight, or 'medium...

A researcher randomly assigns 33 subjects to one of three groups. Group 1 receives technical dietary information interactively from an on-line website. Group 2 receives the same information from a nurse practitioner, while Group 3 receives the information from a video made by the same nurse practitioner. The researcher looked at three different ratings of the presentation: difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation. In particular, the researcher is interested in...

12 subjects in a study were randomly assigned into two equally sized groups. One group was shown a short video on how to fold paper cranes. The other group was given an instruction booklet on how to do so. They were then asked to make paper cranes for the next hour. The number of paper cranes each subject made was recorded and is listed in the table below. The researchers are interested in whether there was a difference in the...

Contracts for two construction jobs are randomly assigned to one or more of three firms A, B, and C. Let Y1 denote the number of contracts assigned to firm A and Y2 the number of contracts assigned to firm B. Recall that each firm can receive 0, 1 or 2 contracts. (b) Find the marginal probability of Y1 and Y2. (c) Are Y1 and Y2 independent? Why? (d) Find E(Y1 − Y2). (e) Find Cov(Y1, Y2)
