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) . Use a significance level of α=0.02 for the test. Assume that the body temperatures are normally distributed for the population of people both before and after taking the drug. Subject 1 2 3 4 5 6 7 Temperature (before) 100.7 99.5 97.7 100.1 99.8 98.4 98.7 Temperature (after) 100 98.7 98 99.6 99.3 98 98.2 Step 1 of 5: State the null and alternative hypotheses for the test Step 2 of 5: Find the value of the standard deviation of the paired differences. Round your answer to two decimal places. Step 3 of 5: Compute the value of the test statistic. Round your answer to three decimal places. Step 4 of 5: Find the p-value for the hypothesis test. Round your answer to four decimal places. Step 5 of 5: Draw a conclusion for the hypothesis test.

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...
