M0/1 A surgeon would like to know how long it takes, on average, to complete a coronary artery bypass surgery. She samples 22 surgeries and logs the time it takes to complete each one, in hours: 3.3, 6.2, 4.3, 4.5, 2.6, 3.7, 4.3, 3.3, 4.6, 4.9, 3.8, 5.7, 4.9, 4.3, 4.2, 3.8, 5.1, 4.5, 5.2, 4.9, 3.9, 4.2 Construct a 91% confidence interval for the average time it takes to complete a koronary artery bypass surgery. S = a II 2 = Margin of Error: E We are 91% confident that the mean amount of time it takes to complete a coronary bypass sugery is between hours. hours and
