The drug OxyContin (oxycodone) is used to treat pain, but it is dangerous because it is addictive and can be lethal. In clinical trials, 227 subjects were treated with OxyContin and 52 of them developed nausea (based on data from Purdue Pharma L.P.). Use a 0.04 significance level to test the claim that more than 20% of OxyContin users develop nausea. Does the rate of nausea appear to be too high? Use the p-value method.
