Customers arrive at the drive-through window at McDonalds restaurant at the rate of 4 every 10 minutes. The average service time is 2 minutes. The Poisson distribution is appropriate for the arrival rate and service times are exponentially distributed. If a second/new drive-through window is to be considered, only one line would be formed. Also, the clerk at the new window would work at the same rate as the current one. Help the restaurant manager find the following performance parameters:

Sparagowski & Associates conducted a study of service times at the drive-up window of fast-food restaurants. The average time between placing an order and receiving the order at McDonald's restaurants was 2.78 minutes (The Cincinnati Enquirer, July 9, 2000). Waiting times, such as these, frequently follow an exponential distribution. 1. What is the probability that a customer's service time is less than 2 minutes? 2.

To reduce this proportion, the manager assigns an additional employee to assist with drive-through orders. During the next month, the manager will collect and random sample of drive through times...

A fast-food restaurant manager wants to see the average bill per car passing through the drive-thru increase. Historically, cars spend an average of $12.39. After implementing the new process employees must follow for each car in the drive-thru, the manager randomly selects 40 cars and finds the mean bill is $12.87 with a standard deviation of $3.92. Does this sample evidence suggest the new process results in a higher ticket price per car? Use a 0.05 level of significance.
