13. The probability that a customer entering an electronics store will make a purchase is equal to p ¼ .15, and customers’ decisions whether to purchase electronics equipment are jointly independent random variables.

(a) Simulate the buying behavior of 10 customers entering the store using the following 10 outcomes from a Uniform(0,1) computer random number generator:

(.4194,.3454,.8133,.1770,.5761,.6869,.5394,.

5098,.4966,.5264).

(b) Calculate the sample mean and sample variance, and compare them to the appropriate population mean and variance.
