7 Suppose that the manufacturer of a drug claims that more than 90% of patients will be healed within 8 weeks. In randomly sampled clinical trials, 235 of 250 patients were healed within 8 weeks. Our goal is to test the manufacturer's claim at a significance level of 0.01. a. Check the assumptions required to test the manufacturer's claim. b. Construct the null and alternative hypotheses. c. Compute the test statistic. d. Apply the critical value or p-value approach to reach a conclusion. (Note: Complete your approach by hand and verify the result with the calculator) e. State your conclusion.
