The first three answers are correct. Need the final two.
Problem 10-16 Customers enter the camera department of a store at the average rate of nine per hour. The department is staffed by one employee, who takes an average of 3.0 minutes to serve each arrival. Assume this is a simple Poisson arrival, exponentially distributed service time situation. Use Exhibit 10.9. a-1. As a casual observer, how many people would you expect to see in the camera department (excluding the...

A market researcher selects 10 customers at random to participate in a wine-tasting test. Each customer is blindfolded and asked to take a drink out of each of two glasses, one containing an expensive wine and the other containing a cheap wine. The customers are then asked to identify the more expensive wine. If the customers have no ability whatsoever to discern the more expensive wine, what is the probability that the more expensive wine will be correctly identified by...

Do you take the free samples offered in supermarkets? About 62% of all customers will take free samples. Furthermore, of those who take the free samples, about 35% will buy what they have sampled. Suppose you set up a counter in a supermarket offering free samples of a new product. The day you were offering free samples, 313 customers passed by your counter. (Round your answers to four decimal places.) (a) What is the probability that more than 180 will...
