If there is someone that can please assist me! I have posted this statistics question 3 times and they keep saying it is a writing assignment. THIS QUESTION IS NOT A WRITING ASSIGNMENT. It is a STATISITCS problem. i am stuck and confused and just needing to see how you solve this! if you do not know how to do it then please leave it for someone else but this is NOT a writing assignment! i will also be glad to rate your work! Suppose that, on average, 2 people in 1000 make a numerical error in preparing their income tax return. If 8000 returns are selected at random and examined, find the probability that 12, 13, or 14 of them contain an error.[Click here to view page 1 of the table of Poisson probability sums.][Click here to view page 2 of the table of Poisson probability sums.]The probability that 12, 13, or 14 income tax returns contain an error is [____]. (Round to four decimal places as needed.)

Note: Hi there! Thank you for posting the question. As the Poisson distribution tables are not give, we have sued excel to solve this question.Consider that the random variable X defines the number of people, who make a numerical error. According to the question, 2 people in 1,000 makes a numerical error. Thus, the success probability is p = 2/1,000 = 0.002. Now, the sample size of n = 8,000 is too large and the success probability is too small. Thus, it can be approximated to a Poisson distribution with average λ = np = (8,000)(0.002) = 16. Hence, in this case X follows Poisson distribution with parameter λ = 16. The probability that 12, 13 or 14 income tax returns contain an error is, Therefore, the probability that 12, 13 or 14 income tax returns contain an error is 0.2405.
