Question

The assumption of exponentially distributed service times indicates that a. service time increase at an exponential rate as the waiting line grows. b. 37% of the service times are less than the mean service time. c. 63% of the service times are less than the mean service time. d. 50% of the service times are less than the mean service time.

Answer 1

option c is correct.

Explanation:

Exponential distribution is large class of probability that includes its member .It also include normal distribution, binomial , gamma , Poisson and many other distribution as well.

Example

It is concerned with the amount of time until any event occur.For example length , in minutes and long distance telephone,

so from given statement it is about time service so option c 63% of the service are less than the mean service is true about it
