Historically, the number of cars arriving per hour at Lundberg’s Car

Wash is observed to be the following:

Number of Cars Arriving Frequency
4 10
5 30
6 50
7 65
8 45
Total: 200

a. Set up a probability distribution table (including the lower end of

the probability range) for the car arrivals.

b. Simulate 25 hours of car arrivals. What is the average number of

arrivals per hour?

c. Repeat part b multiple times (by pressing F9). Over what range

does the average number of arrivals vary?

d. Now simulate 500 hours of car arrivals. What is the average

number of arrivals per hour?

e. Repeat part d multiple times (by pressing F9) Over what range

does the average number of arrivals vary?

f. Do your answers for part c and e differ? Why or why not?

A car wash firm calculates that its daily production (in number of cars washed) depends on the number n of workers it employs according to the formula P = 40n − 0.05n2 cars. Calculate the marginal product of labor at an employment level of 50 workers. HINT [See Example 3.] This means that, at an employment level of 50 workers, the firm's daily production will increase at a rate of  cars per additional worker it hires.
