Compute the mean number of accidents per day. 3)Determine the mean and standard deviation of the variable X in the binomial distribution where n=3 and π=0.90. 4) Assume a Poisson distribution. a. If λ=2.5, find P(X=0). b. If λ=8.0, find P(X=1). c. If λ=0.5, find P(X=2). d. If λ=3.7, find P(X=10). 5) The number of arrivals per minute at a bank located in the central business district of a large city was recorded over a period of 200minutes, with the results shown in the table below. Complete(a) and(b) to the right. Arrivals Frequency 0 14 1 25 2 48 3 43 4 31 5 21 6 10 7 5 8 3 a. Compute the expected number of arrivals per minute.6) A recent survey reported that 58% of18- to29-year-olds in a certain country own tablets. Using the binomialdistribution,a. What is the probability that in the next six18- to29-year-olds surveyed, four will own atablet?7) Suppose that you and two friends go to arestaurant, which last month filled approximately 81 % of the orders correctly.a. What is the probability that all three orders will be filledcorrectly?8) Atoll-free phone number is available from 9 a.m. to 9 p.m. for your customers to register complaints about a product purchased from your company. Past history indicates that an average of 1.0 calls are received per minute.What properties must be true about the situation described here in order to use the Poisson distribution to calculate probabilities concerning the number of phone calls received in a1-minute period? Select all the assumptions for a Poisson distribution. Multiple Choice, Choices are below (A,B,C, or D)A.The number of phone calls received in a given1-minute period is independent of the number of phone calls received in any other1-minute period.B.At least 30 calls are received.C.The probability that two or more phone calls received in a time period approaches zero as the length of the time period becomes smaller.D.The probability of a phone call is the same in any given1-minute period.
