At a significance level of 0.02 on the average, did the women enrolled in the program  have diastolic blood pressure that exceeds the value of 75? ANS: GIVEN:    n = 60    ;   d = 42    x = 101    ;  a = 0.02      SOLUTION: Null & alternate hypothesis Ho : µ = 75 H1 : µ > 75 Level of significance = a = 0.02 Test statistic      t = (x - µ)/ d/vn      t = (101- 75)/ 42/v60      t = 4.79  CRITICAL REGION:      t > ta(n-1)      t > t 0.02(60-1)      t...

A:MAKING A FORMAL STATEMENT FOR NULL HYPOTHESIS: In hypothesis testing,we must state the assumed or hypothesized value of the population parameters before we began sampling.The assumption we wish to test is called the NULL HYPOTHESIS and is symbolized "Ho" or "H sub-zero". Suppose we want to test the hypothesis that the population mean is equal to 500.We would symbolize...
