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 94% of patients taking the drug are healed within 8 weeks. In clinical trials, 212 of 223 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the alpha equals 0.05 level of significance. Question content area bottom Part 1 Because np 0 left parenthesis 1 minus p 0 right parenthesisequals 12.6 greater than 10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) Part 2 What are the null and alternative hypotheses? Upper H 0: p equals 0.94 versus Upper H 1: p greater than 0.94 (Type integers or decimals. Do not round.) Part 3 Find the test statistic, z 0. z 0equals enter your response here (Round to two decimal places as needed.)
