Question

Exercises#4 It has been claimed that the mean weight of women students at a college is 55.5Kg. Professor Ali does not believe the statement and sets out to show the mean weight is not 55.5Kg. To test the claim he collects a random sample of 200 weights from among the women students. A sample means of 54.75kg results. Is this sufficient evidence for Professor Ali to reject the statement? Use α 0.01 and σ 5.5Kg.
