A mechanic installs automobile tires on a first-come first-serve basis. The total time a customer needs to wait for the installation to be completed follows the normal distribution with a mean time of 106.3 minutes and a standard deviation of 18.5 minutes. What is the probability that a randomly selected customer will wait between 80 and 95 minutes for his or her tires to be installed? A. 0.3455 B. 0.2960 C. 0.1245 D. 0.1931 Suppose the round-trip airfare between Philadelphia...

1.) Tire Kingdom installs automobile tires on a first-come first-served basis. A random sample of 45 customers experienced an average wait time of 102.7 minutes. Assume that the standard deviation of total wait time for all customers is 17.0 minutes. Determine the margine of error for a 90% confidence interval for this sample. 2.)

Consider a simple queuing system in which customers arrive randomly such that the time between successive arrivals is exponentially distributed with a rate parameter l = 2.8 per minute. The service time, that is the time it takes to serve each customer is also Exponentially distributed with a rate parameter m = 3 per minute. Create a Matlab simulation to model the above queuing system by randomly sampling time between arrivals and service times from the Exponential Distribution. If a...
