Question
5.6.5 WP An article in Knee Surgery Sports Traumatology,
Arthroscopy ["Effect of Provider Volume on Resource Utilization
for Surgical Procedures" (2005, Vol. 13, pp. 273–279)] showed a
mean time of 129 minutes and a standard deviation of 14 min-
utes for ACL reconstruction surgery for high-volume hospitals
(with more than 300 such surgeries per year). If a high-volume
hospital needs to schedule 10 surgeries, what are the mean and
variance of the total time to complete these surgeries? Assume
that the times of the surgeries are independent and normally
distributed.
