A hypothesis test was made of H0: μ1 = μ2 versus H1: μ1 not equal to μ2 . Independent random samples were drawn from approximately normal populations. The sample means were top enclose X subscript 1 end enclose space equals 73 and top enclose X subscript 2 end enclose space equals 71 . The population standard deviations were σ1 = 4 and σ2 = 3. The sample sizes were n1 = 24 and n2 = 18, then the value of the test statistic Z is given by:   2.37   4.9   3.68   2.78
