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: 6.9, 7.5, 4.9, 6.5, 4.4, 6.2, 2.4, 7, 6.2, 5.5, 6.2, 7.3, 7.3, 8.5, 6.9, 5.6, 4.1, 3.6, 5.4, 6.7, 5.4, 5.3, 6.5, 3.2, 5.2, 8.1, 5.7, 4.5, 5.9, 2.3 Assuming the population standard deviation is σ=1.25σ=1.25, construct a 87% confidence interval for the average time it takes to complete a coronary artery bypass surgery. xˉ=x̄= α/2=
