93.  After a period of apprenticeship, an organization gives an exam that must be passed to be eligible for membership. Let p = P(randomly chosen appren- tice passes). The organization wishes an exam that most but not all should be able to pass, so it decides that p = .90 is desirable. For a particular exam, the relevant hypotheses are H0: p = .90 versus the alter- native Ha: p -:f .90. Suppose ten people take the exam, and let X = the number who pass.
a.  Does the lower-tailed region {0, 1,..., 5} spec- ify a level .01 test?
b.  Show that even though Ha is two-sided, no two- tailed test is a level .01 test.
c.   Sketch a graph of b(p') as a function of p' for this test. Is this desirable?
