Kindly answer in excel sheet
(I am providing the EXCEL commands for this
question.)
Here, X = arrivals to a bank ATM. Here,
= 6 per 10 minutes = mean. Now, X ~ Poisson(
= 6).
(a) The probability that in a given 10 minute segment, three
customers will arrive at the ATM = 0.0892.
EXCEL command: =POISSON(3,6,0).
(b) Here,
= 12 per 20 minutes = mean. Now, X ~ Poisson(
= 12). The probability that fewer than five customers will arrive
in a 20 minute segment = 0.0076.
EXCEL command: =POISSON(4,12,1).

Arrivals to a bank automated teller machine (ATM) are distributed according to a Poisson distribution with a mean equal to four per 5 minutes. Complete parts a and b below. a. Determine the probability that in a given -minute segment, will arrive at the ATM. The probability is nothing. (Round to four decimal places as needed.) b. What is the probability that fewer than customers will arrive in a -minute segment? The probability is
Arrivals to a bank automated teller machine (ATM) are distributed according to a Poisson distribution with a mean equal to five per 10 minutes. Determine the probability that in a given 10-minute segment, two customers will arrive at the ATM. a. 0.0842 b.0.1247 c.0.0028 d. 0.9942 what is the probability that fewer than two customers will arrive in a 30 minutes segment? a. 0.0028 b. 0.0000 c. 0.0842 d. 0.9942
The amount of time that a drive-through bank teller spends on a customer is a random variable with a mean u = 7.9 minutes and a standard deviation o = 3.6 minutes. If a random sample of 81 customers is observed, find the probability that their mean time at the teller's window is (a) at most 7.3 minutes; (b) more than 8.7 minutes; (c) at least 7.9 minutes but less than 8.3 minutes.

Problem 15-1 Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. What is the mean or expected number of customers that will arrive in a five-minute period? λ = per five minute period Assume that the Poisson probability distribution can be used...
7. An urn contains nine blue balls and six yellow balls. If five balls are selected randomly without being replaced probability that of the balls selected, one of them will be blue and four of them will be yellow? (2 points) N-15 n=5 8. The mean number of errors per page made by a member of the word processing pool for a large company is thought 2.6 with the number of errors distributed according to a Poisson distribution. If a...
The number of people arriving at an ATM can be described by a Poisson Distribution. It is known that the mean number of arrivals in thirty minutes is 11.0. Determine the probability that ten people or less arrive in 30 minutes. Enter your answer as a decimal rounded to three places.
Many of a bank’s customers use its automatic teller machine to transact business after normal banking hours. During the early evening hours in the summer months, customers arrive at a certain location at the rate of one every other minute. This can be modeled using a Poisson distribution. Each customer spends an average of 83 seconds completing his or her transactions. Transaction time is exponentially distributed. a. Determine the average time customers spend at the machine, including waiting in line...
Customers arrive at a service window according to Poisson process with an average of 0.2 per minute. What is probability that the time between two successive arrivals is less than 6 minutes?
The average number of customers arriving at a drive-through window of a bank branch is 39 per hour during lunch hours. Use X to denote the number of arrivals in a 5 minute time interval. Assume the customers arrive independently and the number of arrivals within each 5 minutes follows a Poisson distribution. Keep at least 4 decimal digits if the result has more decimal digits. I AM JUST LOOKING FOR WHAT FUNCTION/EQUATION TO PUT INTO MY CALCULATOR TO GET...
Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. The mean number of births per minute in a country in a recent year was about seven. Find the probability that the number of births in any given minute is (a) exactly five, (b) at least five, and (c) more than five. (a) P(exactly five)...
