Suppose that for years the mean of population 1 has been accepted to be the same as the mean of population 2. but now population 1 is believed to have a greater mean than population 2. Letting o = 0.05 and assuming the populations have equal variances and x is approximately normally distributed. use the following data to test this belief. Sample 1 Sample 2 43.6 45.7 40.1 36.4 44.0 49.1 42.2 42.3 45.2 45.6 43.1 38.8 40.8 46.5 37.5 43.3 48.3 45.0 41.0 40.2 Provide a test statistic = [53'3\"] V and therefore we [ Select ] v Reject the null hypothesis l Fail to reject the null hypothesis l
