A certain outpatient medical procedure has five steps that must be performed in sequence.
Step Mean (Minutes) Standard Deviation
Patient check-in 12 3
Pre-op preparation 27 6
Medical procedure 23 7
Recovery 43 6
Check-out and discharge 19 3
Assuming that the time (in minutes) required for each step is an independent random variable, find the mean and standard deviation for the total time. (Round standard deviation answer to 1 decimal place.)
Mean ______ Minutes
Standard Deviation __________ Minutes
