Question
Transcribed Image Text: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, 228 of 235 patients
suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the a=0.05 level of significance.

Because npo (1-Po) = 11.2 > 10, the sample size is less than 5% of the population size, and the sample
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
