Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6014 patients treated with this drug, 159 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction?
