1.	Problem 15-27 (Algorithmic): Gubser Welding, Inc., operates a welding service for construction and automotive repair jobs. Assume that the arrival of jobs at the company's office can be described by a Poisson probability distribution with an arrival rate of three jobs per 8-hour day. The time required to complete the jobs follows a normal probability distribution, with a mean time of 2.2 hours and a standard deviation of 1 hour. Answer the following questions, assuming that Gubser uses one w...
