Solve the below:
Q: An article in Knee Surgery Sports Traumatol Arthrosc["Effect of Provider Volume on Resource Utilization for Surgical Procedures"] showed a meantime of 129 minutes and a standard deviation of 14 minutes foranteriorcruciate ligament (ACL) reconstruction surgery at high volumehospitals (with more than 300 such surgeries per year)
(a) What is the probability that your ACL surgery at a high volume hospital requires a time more than two standard deviations above the mean?
(b) What is the probability that your ACL surgery at a high volume hospital is completed in less than 100 minutes?
(c) The probability of a completed ACL surgery at a high-volume hospital is equal to 95% at what time?
(d) If your surgery requires 199 minutes, what do you conclude about the volume of such surgeries at your hospital? Explain.
