5. An experiment was designed to sec if regular exercise can hclp lower blood pressure for patients with high blood pressure. A rescarcher wanted to test this thcory and told a groen of volunteers with high blood pressure that exercise may work better than any other treatment for high blood pressure. The researcher assigned participants to two groups. One group was enrolled in a physical fitncss program and the other group was prescribed a placcbo. At the end of the month, the blood pressure in the volunteers, on average, decreascd approximatcly the same from the blood pressure at the beginning of the month for both groups of participants. Which of the following is true about this experiment? Because the researcher is the one that picks the group of patients that exercisc, the paticnts are blinded to the treatment and the decrease in blood pressure is caused by the exercise routine or the mcdicinc. b. a. The fact that the average decrease was not significantly different for both groups may be due to the placcbo effect, so it may be true that exercise works better than any other treatment. Because the test results were not significantly different, there is rcason to believe that exercisc works better than any other treatment. The experiment is well-designed, but the researcher nceds to incrcase the time of the experiment to a whole ycar. c. d.
