Independent samples are drawn from from each of two populations. The sample means, standard deviations and sample sizes are: X bar1 = 28 , SD1=1.4 , n1= 20; and Xbar2 = 27 , SD2= 1.0 , n2=30. Test the hypothesis that there is no difference between the two populations at the a= 0.05 level, i.e, H0:M1 = M2 vs HA:M1 ≠ M2. Whats your conclusion? Why do you say that ? USe the p-value method
