The fоllоwing dаtа cоncerns а randomized controlled trial. Two groups of 100 men with systolic blood pressure in the 120 to 130 range and diastolic blood pressure in the 80 to 90 range are treated to reduce the “pre-hypertensive” state. The men are in the age range 30 to 40 years. The control group 1 is given placebo and the experimental group 2 is given a treatment .to reduce blood pressure. Assume the standard deviations are equal for both groups. The results are as follows: barX1 = 131, barX2 = 124, Sx1 = 21, Sx2 = 24, n1 = 100, n2 = 100 Analyze this data to determine if the treatment significantly reduces blood pressure. Find null and alternative hypotheses for this test. The answer is in the form (Ho, Ha.).
