Question 5 The Department of Health is concerned about the consultant fee charged by doctors. The department has set a maximum charge of R246 per visit that doctors may charge their patients. A random sample of 368 doctors was selected and it was found that the average consultation fee the doctors charged was R328 with a population standard deviation of R29. Assume the consultation fees charged by the doctors are normally distributed. Use the hypothesis testing outlines below to test, at the 5% level of significance, whether the majority of doctors charged more than the department's set maximum fee. Use a critical value of 1.645.
