The drug Tamiflu (oseltamivir phosphate) is used to attack the influenza virus to reduce symptoms for patients. The manufacturer label states that 6% 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 724 patients treated with Tamiflu, 72 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.
