This problem is based on information taken from The Merck Manual (a reference manual used in most medical and nursing schools). Diltiazem is a commonly prescribed drug for hypertension. However, diltiazem causes headaches in about 12% of patients using the drug. It is hypothesized that regular exercise might help reduce the headaches. If a random sample of 211 patients using diltiazem exercised regularly and only 19 had headaches, would this indicate a reduction in the population proportion of patients having headaches? Use a 1% level of significance. State the null and alternate hypotheses. H0: p = 0.12; H1: p 0.12 H0: p = 0.12; H1: p > 0.12 H0: p > 0.12; H1: p = 0.12 H0: p = 0.12; H1: p < 0.12 H0: p < 0.12; H1: p = 0.12
