Question

23. A medical researcher claims that calcium supplements can decrease the systolic blood pressures of men. In part of the study, 10 randomly selected men are given a calcium supplement for 12 weeks. The table shows the systolic blood pressures (in millimeters of mercury) of the 10 men before and after the 12-week study. At ? = 0.10, is there enough evidence to support the medical researcher's claim? (Source: The Journal of the American Medical Association) Patient: 1, 2, 3, 4, 5 Systolic blood pressure (before): 107, 110, 123, 129, 112 Systolic blood pressure (after): 100, 114, 105, 112, 115 Patient: 6, 7, 8, 9, 10 Systolic blood pressure (before): 111, 107, 112, 136, 102 Systolic blood pressure (after): 116, 106, 102, 125, 104
