(b) Construct a 99% confidence interval for the proportion of patients ages 50 and older who experience a failure within the first 2 years after receiving this type of defibrillator. (Round your answers to three decimal places.) Interpret the interval. O We are 99% confident that the proportion of all patients who experience a failure after receiving this type of defibrillator is within this interval. We are confident that the proportion of all patients ages 50 or older who experience a failure within the first two years after receiving this type of defibrillator is within this interval at least 99% of the time. We are 99% confident that the proportion of all patients ages 50 or older who experience a failure within the first two years after receiving this type of defibrillator is within this interval. We are confident that 99% of all patients ages 50 or older who experience a failure within the first two years after receiving this type of defibrillator is within this interval.

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 experienced within 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 two samples as representative of patients in the two age groups who receive this type of defibrillator.
