Suppose that a team of doctors is planning a study to test the effects of antihypertensive medication and exercise on blood pressure. The three dosages of antihypertensive medication are 40 mg, 20 mg, and 0 mg (placebo). The three levels of exercise are 20 minutes of exercise five days a week, 20 minutes of exercise three days a week, and 0 minutes of exercise. A random sample of 450 adults with high blood pressure were selected at random, and 50 were assigned to each of the nine combinations of antihypertensive medication and exercise. Which of the following statements about this experiment are true?

(a).The subjects of the experiment are the different means of treating blood pressure.

(b)The treatments are the nine combinations of the three dosages of antihypertensive medication and the three levels of exercise.

(c)The factors are the nine combinations of the three dosages of antihypertensive medication and the three levels of exercise.

(d)The factors are antihypertensive medication and exercise.

(e)The treatments are antihypertensive medication and exercise.

(f)The subjects of the experiment are the 450 adults with high blood pressure.

1. DDT is a pesticide banned in the United States for its danger to humans and animals. In an experiment on the impact of DDT, six rats were exposed to DDT poisoning and six rats were not exposed. For each rat in the experiment, a measurement of nerve sensitivity was recorded. The researchers suspected that the mean nerve sensitivity for rats exposed to DDT is greater than that for rats not poisoned. The data follow: Poisoned rats: 12.207 16.869 25.050...
