Due to stress, many patients who undergo major elective surgery experience an increase in blood pressure before their scheduled operations. The ABC hospital has started a new yoga program intended to reduce stress and blood pressure. A random sample of 50 patients who know they must undergo a major elective surgery was enrolled in this program. The systolic blood pressure of each patient was measured prior to starting the yoga program. At the end of the yoga program, the systolic blood pressure of each patient was measured again. Question: What statistical test can be used to test if the yoga program is effective in reducing blood pressure?(choose one answer): A. The t-test for two independent samples B. C. The one-sample test for the binomial proportion C. The F-test for the equality of two variances D. The paired t-test
