Psychologists interested in whether meditation can be used as a treatment for high blood pressure observed a simple random sample of retirement community residents. Of the 100 that practiced daily meditation, 33 had high blood pressure. Of the 300 that did not practice daily meditation, 150 had high blood pressure. The following test was performed and the results are shown. Null: p1 - p2 = 0, Alt: p1 - p2 < 0. p1 = prop. of daily people who have high blood press, p2 = prop. of non-daily people who have high blood press. Checking your conditions, and resulting with a z-score of -2.96 and p-value of 0.0016, do these data provide convincing statistical evidence hat daily meditation would reduce high blood pressure in people like these?
