Question

please answer question b) payong careful attention to the notation.

Simon plays golf at his local 18-hole golf course. In his last 20 visits, he works out that he has scored above par on 60% of the holes he has played. For each visit, he models the number 3 es where he scores above par, H, using a binomial distribution: H- B(18, 0.6). Give one assumption that Simon has made in modelling H in this way. a) b) Each time Simon plays golf, he tests to see if the probability that he scores above par has changed. Stating your hypotheses clearly, find the critical region for such a test at the 10% significance level.
