A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 95% of patients taking the drug are healed within 8 weeks. In clinical trials, 215 of 224 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the a = 0.1 level of significance. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). Because npo (1- Po) = 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis V satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: VI versus H,: (Type integers or decimals. Do not round.) Determine the test statistic, zn- Zn = (Round to two decimal places as needed.) Determine the critical value(s). Select the correct choice below and fill in the answer box to complete your choice (Round to two decimal places as needed.) O A. ±Za/2 = ± O B. Za = Choose the correct conclusion below. O A. Reject the null hypothesis. There is insufficient evidence to conclude that more than 95% of patients taking the drug are healed within 8 weeks. O B. Do not reject the null hypothesis. There is sufficient evidence to conclude more than 95% of patients taking the drug are healed within 8 weeks. OC. Do not reject the null hypothesis. There is insufficient evidence to conclude that more than 95% of patients taking the drug are healed within 8 weeks. O D. Reject the null hypothesis. There is sufficient evidence to conclude that more than 95% of patients taking the drug are healed within 8 weeks.
