t 1 myopenmath.com 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: 4.6, 4.2, 3.2, 3.9, 6.1, 6.4, 3.5, 3.5, 3.8, 4.2, 5.3, 6.1, 4.4, 3.9, 2.4, 3.9, 3.3, 5.1, 4.4, 2.4, 4.3, 1.4 Assuming the population standard deviation is or = 0.97, construct a 87% confidence interval for the average time it takes to complete a coronary artery bypass surgery. We are 87% confident that the mean amount of time it takes to complete a coronary bypass sugery is Submit
