1. Make the conclusion:
Test Stat = 2.2 , Dist = Z, n = 50, significance level = .02 , > Test
Critical Value = [ Select ] ["-2.3", "-2.05 and 2.05", "-2.05", "-2.3 and 2.3", "2.3", "2.05"]
conclusion = [ Select ] ["Fail to reject null hypothesis", "Reject null hypothesis"]
Test Stat = 2.2 , Dist = Z, n = 50, significance level = .02 , ≠ Test
Critical Value = [ Select ] ["2.33", "-2.05 and 2.05", "-2.33 and 2.33", "2.05", "-2.33", "-2.05"]
conclusion = [ Select ] ["reject null hypothesis", "fail to reject null hypothesis"]
Test Stat = -2.2 , Dist = Z, n = 50, significance level = .01 , < Test
Critical Value = [ Select ] ["2.33", "-2.33 and 233", "-2.05", "2.05", "-2.05 and 2.05", "-2.33"]
conclusion = [ Select ] ["fail to reject null hypothesis", "reject null hypothesis"]
Test Stat = 2.3 , Dist = t, n = 50, significance level = .02 , > Test
Critical Value = [ Select ] ["2.40", "2.05", "-2.11", "-2.40 and 2.40", "2.11", "-2.3 and 2.3", "2.33"]
conclusion = [ Select ] ["Reject the null hypothesis", "Fail to reject the null hypothesis"]
Test Stat = 2.3 , Dist = t, n = 50, significance level = .02 , ≠ Test
Critical Value = [ Select ] ["2.33", "-2.33 and 2.33", "-2.40 and 2.40", "2.40", "-2.11 and 2.11", "-2.33", "2.11", "-2.11", "-2.33 and 2.33"]
conclusion = [ Select ] ["reject the null hypothesis", "fail to reject the null hypothesis"]
Test Stat = -2.3 , Dist = t, n = 50, significance level = .01 , < Test
Critical Value = [ Select ] ["-2.33", "-2.40", "-2.11", "-2.05"]
conclusion = [ Select ] ["reject the null hypothesis", "fail to reject the null hypothesis"]
