6. Ibuprofen is the magical headache and inflammation cure-all drug. In clinical trials, 19

out of 863 randomly, independently picked patients taking 200 mg of Ibuprofen daily

complained of vomiting a material that looks like coffee grounds (this is a real side

effect). Suppose that it is known that 1.9% of patients taking competing drugs

complain of vomiting a coffee grounds-like substance. Is there evidence to conclude

that more than 1.9% of Ibuprofen users experience the vomiting side effect at the

α = 0.01 level of significance?
