Let X = the time between two successive arrivals (in minutes) at a drive thru window. Suppose X is exponentially distributed, and that the average time between successive arrivals at the drive thru window is 1.2 minutes. What is the value of lambda, the parameter of exponential distribution? What is the probability that the next drive thru arrival is between 1 to 4 minutes from now? What is the probability that the next drive thru arrival is greater than 2...

Let X = the headway between two randomly selected consecutive cars (sec). Suppose that in a different traffic environment =, the distribution of time headway has the form: f(x) = {k/(x^5) if x >= 1, 0 if x <= 1 A: Determine the value of k for which f(x) is a legitimate pdf. B: Obtain the cumulative distribution function. C: Use the cdf form (b) to determine the probability that headway exceeds 2 sec and also the probability that headway...

1. Suppose that an airline quotes a flight time of 2 hours, 10 minutes between two cities. Furthermore, suppose that historical flight records indicate that the actual flight time between the two cities, x, is uniformly distributed between 2 hours and 2 hours, 20 minutes (uniform distribution). Letting the time unit be one minute, a. What is the mean? b. What is the standard deviation? c. Find P(125 ≤ x ≤ 135) (between 125 minutes and 135 minutes). d. Find...
