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: 3.7, 4.9, 3.9, 5.3, 3.6, 5, 3.1, 5, 5.5, 3.3, 3.4, 2.9, 2.5, 3, 4.4, 3.8, 4, 3.9, 2.9, 4.6, 3.2, 3.3, 3.1, 3.6, 3.8 Assuming the population standard deviation is o = 0.69, construct a 90% confidence interval for the average time it takes to complete a coronary artery bypass surgery. Margin of Error: E = We are 90% confident that the mean amount of time it takes to complete a coronary bypass sugery is hours and hours. between Submit
