Suppose that the mean number of customers who arrive at the check-out counters each minute is 4. Create a Poisson Distribution with u (lamda) = 4 for x = 0 to 20. Compare your results to the histogram.

20 random numbers are generated with a Poisson distribution for u (lamda) = 4. Let the random number represent the number of arrivals at the check-out counter each minute for 20 minutes.

3, 3, 3, 3, 5, 5, 6, 7, 3, 6, 3, 5, 6, 3, 4, 6, 2, 2, 4, 1

a) How many customers were waiting after 5 minutes? 6 minutes? 7 minutes? 8 minutes?

b) Create a table that shows the number of customers waiting at the end of 1 through 20 minutes.
