During the 12 P.M.–1 P.M. noon hour, arrivals at a curbside banking machine have been found to be Poisson distributed with a mean of 1.3 persons per minute. If x = number of arrivals during a given minute, determine the following: Please round (a) to 1 decimal, and (b) through (e) to 4 decimals. a. E(x) = b. P(x = 0) = c. P(x = 1) = d. P(x ≤ 2) = e. P(1 ≤ x ≤ 3) =

Arrivals at a walk-in optometry department in a shopping centre have been found to be Poisson distributed with a mean of 2.71 potential customers arriving per hour. Assuming that the Poisson distribution is reasonable for this situation, where X is the number of arrivals during a given hour. Calculate the probability of at least 19 customers between 2pm and 6pm? Give the answer to the two decimal places.

The number of calls arriving at a switchboard from noon to 1
p.m. during the business days Monday through Friday is monitored
for six weeks (i.e. 30 days). Let X be defined as the number of
calls during that one-hour period. The relative frequency of calls
was recorded and reported as:

(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...
