constant service time model) assume‚ or require‚ that the arrival rate can be described by a Poisson distribution and that the service time can be described by a negative exponential distribution. Equivalently‚ we can say that the arrival and service rates must be Poisson‚ and the interarrival time and the service time must be exponential. In practice‚ one would check for this using a statistical Chi Square test: for problems provided here and in the textbook‚ assume that these distributions hold. Note

Problem 1: A fast-food franchise is considering opening a drive-up window food service operation. Assume that customer arrivals follow a Poisson distribution‚ with a mean arrival rate of 24 cars per hour‚ and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive up to the service window to pay for and receive their order. Compute the following operating characteristics for each

represented as probabilities. Life testing is a general term used to describe the experimentation and statistical analysis performed to investigate failure rates. Probability distributions that are used to model failure times are typically the exponential distribution‚ the gamma distribution‚ the Weibull distribution‚ and the lognormal distribution. Statistical analysis can be employed to make inferences on the failure rates under these distributional assumptions or to make general inferences

That is‚ the ownership of one’s labor is transferred‚ not through due course of law or any other such institution‚ to another person by the act of laboring itself.
