Do you dislike waiting in line? A supermarket chain used computer simulation and information technology to reduce the average waiting time for customers at 2,300 stores. Using a new system, which allows the supermarket to better predict when shoppers wil be checking out, the company was able to decrease average customer waiting time to just 19 seconds. (a) Assume that supermarket waiting times are exponentially distributed. Show the probability density function of waiting time at the supermarket. -(히X. elsewhere 19...
