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 92% of patients taking the drug are healed within 8 weeks. In clinical trials, 222 of 240 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.

Because np 0 left parenthesis 1 minus p 0 right parenthesis equals nothingless than not equals equals greater than 10, the sample size is less than greater than 5% of the population size, and the sample can be reasonably assumed to be random, is given to not be random, is given to be random, cannot be reasonably assumed to be random, the requirements for testing the hypothesis are not are satisfied.
