Suppose that the number of customers ordering take-out at a small restaurant is a Poisson process with rate a = 3.6 customers per hour. Answer the following questions. If necessary, round your answer to four decimal places. (a) Find the probability that there would be at least two customers in a 45-minute period.

A recently conducted survey found that 32% of customers stated that they prefer to buy items that they have seen advertised on television. Suppose two hundred (200) customers were randomly selected, use an appropriate approximation to determine the probability that at most 50 of the customers prefer to buy items that they have seen advertised on television.

In a shopping mall an average of 3 out of every 5 customers use visa credit cards. A sample of 10 customers is selected. Find the probability that exactly 6 customers use visa credit card. Find the probability that less than 9 customers use visa credit card. Now assume that a sample of 50 customers are selected. Find the smallest value of n such that P(X<n) ≥ 0.9, where the random variable X represents the number of customers who uses...

(1 point) You are interested in finding out the mean number of customers entering a 24-hour convenience store every 10-minutes. You suspect this can be modeled by the Poisson distribution with a a mean of = 3.59 customers. You are to randomly pick n = 57 10-minute time frames, and observe the number of customers who enter the convenience store in each. After which, you are to average the 57 counts you have. That is, compute the value of X...
