A šurgeon would like to know how long it takes, on average, to complete a coronary artery bypas surgery. She samples 30 surgeries and logs the time it takes to complete each one, in hours: 4.7, 4.6, 4.1, 4.7, 4.7, 4.9, 4.8, 4.9, 5.7, 5.2, 4.5, 5, 4.9, 4.4, 4.7, 5.1, 5.3, 5.3, 4.2, 4.8, 4.7, 5.4, 5.4, 4.5, 5.1, 4.7, 4.6, 4.6, 4.4, 5.2 Construct a 93% confidence interval for the average time it takes to complete a coronary artery bypass surgery. S = %3D Margine of Error: E = We are 93% confident that the mean amount of time it takes to complete a coronary bypass sugery is between hours and hours.

A surgeon would like to know how long it takes, on average, to complete a coronary artery bypass
surgery. She samples 30 surgeries and logs the time it takes to complete each one, in hours:
4.7, 4.6, 4.1, 4.7, 4.7, 4.9, 4.8, 4.9, 5.7, 5.2, 4.5, 5, 4.9, 4.4, 4.7, 5.1, 5.3, 5.3, 4.2, 4.8, 4.7, 5.4, 5.4, 4.5,
5.1, 4.7, 4.6, 4.6, 4.4, 5.2
Construct a 93% confidence interval for the average time it takes to complete a coronary artery
bypass surgery.
S =
