Suppose that scores on the standardized test in Physics are taken by students from A and O are N(A, 9) and N(O, 16) respectively. Two samples were drawn with n = 9, xA = 83.7 from A, and m = 7, xO = 79.7 from O. Find the 95% CI for A O.
At = 0.05, can it be concluded that the students from O perform better in Physics than students from A?
