A medical researcher is studying the effects of a drug on blood pressure. Subjects in the study have their blood pressure taken at the beginning of the study. After being on the medication for 4 weeks, their blood pressure is taken again. The change in blood pressure is recorded and used in doing the hypothesis test. Change: Final Blood Pressure - Initial Blood Pressure The researcher wants to know if there is evidence that the drug reduces blood pressure. At the end of 4 weeks, 33 subjects in the study had an average change in blood pressure of -2.9 with a standard deviation of 5.4. Find the p -value for the hypothesis test. Your answer should be rounded to 4 decimal places.

A medical researcher is investigating the effect of drinking
coffee on systolic blood pressure. The researcher assumes the
average systolic blood pressure is 120 mmHg. For a random sample of
200 patients, the researcher takes two measurements of systolic
blood pressure. The first systolic blood pressure measurement is
taken during a week when the patients drink no coffee, and the
second systolic blood pressure measurement is taken during a week
when the patients drink at least two cups of coffee....

A medical researcher believes that a drug changes the body's
temperature. Seven test subjects are randomly selected and the body
temperature of each is measured. The subjects are then given the
drug, and after 30 minutes, the body temperature of each is
measured again. The results are listed in the table below. Is there
enough evidence to conclude that the drug changes the body's
temperature? Let d=(body temperature after taking drug)−(body
temperature before taking drug) d=(body temperature after taking
drug)−(body...
