A lecturer wants to know if his inductor statistics class has a good grasp of the basic maths done at matric level. The students understanding would help the lecturer to plan for the courses to be undertaken. Nine students were chosen at random from the class and given a maths profiency test. The lecturer wants the class to be able to score at least 70 on the test to show a good grasp of basic maths. The selected nine students get scores of 92, 75, 85, 68, 58, 60, 83, 95 and 57.Use the p-value approach to find out whether the mean score for the class on the the test would be at least 70 at an alpha of 1%
