Question
A surgeon would like to know how long it takes, on average, to complete a coronary artery bypass surgery. She samples 27 surgeries and logs the time it takes to complete each one, in hours: 6.3, 3.4, 3.6, 5, 3.5, 4.5, 6.2, 5, 4.3, 2.8, 4.2, 4.7, 5.3, 4, 6.3, 3.5, 5.1, 4.5, 2.8, 2.6, 5.4, 2.8, 6.1,6.1, 4.1, 5.7, 4.4 Assuming the population standard deviation is o = 1.1, construct a 95% confidence interval for the average time it takes to complete a coronary artery bypass surgery. Margin of Error: E = We are 95% confident that the mean amount of time it takes to complete a coronary bypass sugery is between hours and hours.
