A pharmaceutical company claims 90% success rate of a newly invented drug to treatarthritis pain. To examine the claim, a doctor administered the prescribed dose to 10arthritis patients. She observed Y, the number of participants for which the drug waseffective. A test is defined so as to reject Ho: p = 0.9 in favour of Ha: p < 0.9 bythe rejection region {y < k} where k is a positive integer. Note that p is the populationproportion of arthritis patients for which the drug was effective.(d) Find the power of the test for p = 0.3, 0.5, 0.7, 0.9.(e) Sketch a graph of the power function against p (0 < p ≤ 1), and comment on howthe power changes as p changes. [Hint: You may use Table 1 in Appendix 3 ofWMS.]

Your company manufactures plastic wrap for food storage. The tear resistance of the wrap, denoted by X, must be controlled so that the wrap can be torn off the roll without too much effort but it does not tear too easily when in use. In a series of tests (see data table below), 15 rolls of wrap are made under carefully controlled conditions and the tear resistance of each rool is measured. The results are used as the basis of a quality assurance specification. If X for a subsequently produced roll falls more than two standard deviations away from the test period average, the process is declared out of specification and production is suspended for routine maintenance.
