216 is not correct An article describes several studies of the failure rate of defibrillators used in the treatment of heart problems. In one study conducted by the Mayo Clinic, it was reported that failures were experiencedwithin the first 2 years by 15 of 81 patients under 50 years old and 19 of 356 patients ages 50 and older who received a particular type of defibrillator. Assume it is reasonable to regard these twosamples as representative of patients in the two age groups who receive this type of defibrillator. (c) Suppose that the researchers wanted to estimate the proportion of patients under 50 years old who experience a failure within the first 2 years after receiving this type of defibrillator to within0.03 with 95% confidence. How large a sample should be used? Use the results of the study as a preliminary estimate of the population proportion. (Round your answer up to the nearest wholenumber.)patients
