I'm confuse please help me

A surgeon would like to know how long it takes, on average, to complete a coronary artery bypass surgery. She samples 28 surgeries and logs the time it takes to complete each one, in hours: 4.9, 4.3, 4.3, 4.9, 4.7, 3.5, 5.5, 4.5, 3.2, 4, 4.6, 3.7, 4, 4.6, 3.8, 4.3, 4.8, 3.4, 4.1, 3.6, 3.7, 4.1, 4.6, 4.8, 4.2, 4.9, 3.6, 4.4 Assuming the population standard deviation is o = 0.58, construct a 85% confidence interval for the average time it takes to complete a coronary artery bypass surgery. N Q Margin of Error: E = We are 85% confident that the mean amount of time it takes to complete a coronary bypass sugery is between hours and hours
