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, 213 of 224 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the α = 0.1 level of significance.

Because npo (1 - Po) = 12.6 > 10, the sample size is less than can be reasonably assumed to be random, the requirements for testing the hypothesis (Round to one decimal place as needed.)

The manufacturer label states that 7% of patients will develop nausea as a side effect. Patients report that nausea occurs at a higher rate than the label indicates. In clinical trials, among 670 patients treated with Tamiflu, 82 experienced nausea as a side effect. Using an α=0.05 level of significance, complete the following steps to determine whether the rate of developing nausea is higher than the manufacturer’s label.
