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 205 patients using diltiazem exercised regularly and only 18 had headaches, would this indicate a reduction in the population proportion of patients having headaches? Use a 1% level of significance. A-What is the value of the sample test statistic? (Round your answers to two decimal places.) B- Find the P-value of the test statistic. (Round your answers to four decimal places.)
