A surgeon would like to know how long it takes, on average, to complete a coronary artery bypass surgery. She samples 25 surgeries and logs the time it takes to complete each one, in hours: 6.4, 5.6, 7.8, 5, 6.5, 5.4, 6.9, 3.2, 6.7, 5.1, 6.8, 5, 5.8, 6.3, 5.3, 6.2, 6.4, 5.9, 5.9, 6.9, 6.3, 5.5, 7, 4.6, 4.9 Assuming the population standard deviation is o = 1.16, construct a 89% confidence interval for the average time it takes to complete a coronary artery bypass surgery. N Q 2 N /D Margin of Error: E = We are 89% confident that the mean amount of time it takes to complete a coronary bypass sugery is between hours and hours
