The amount of time taken by a machine repair person to repair a particular machine is a random variable with an exponential distribution with a mean of 1 hour. The repair persons employer pays the repair person a bonus of 2 whenever a repair takes less than 1/4 hours, and a bonus of 1 if the repair takes between 1/4 and 1/2 hours. Find the average bonus received per machine repaired (nearest) .1). A) .3 B) .4 C) .5 D) .6 E) .7

The Acme Machine Shop has five machines that periodically break down and require service. The average time between breakdowns for any one machine is 4 days, distributed according to an exponential distribution. The average time to repair a machine is 1 day, distributed according to an exponential distribution. One mechanic repairs the machines in the order in which they break down. Use q.xls. a. Determine the probability that the mechanic is idle. (Hint: Pn is given in q.xls, and is...
