1. Suppose you are a technician, whose repair time on a given job is said to follow an exponential distribution with expected time θ = 3 hours.

What is the variance of the true time? b. Now say you charge $250 per hour. How many dollars do you expect to make on a given job? How many dollars do you expect to make finishing all the jobs you have lined up
