The number of babies born each day in a certain hospital isPoisson distributed with λ = 6.9.(a) During a particular day, are 7 babies more likely to beborn than 6 babies?(b) What is the probability that at most 15 babies will be born during a particular day?

Question 20. A town has a clinic where people go to donate blood. One third of the persons donating blood at each of these clinics have O+ blood. What is the probability that in a randomly chosen day, it takes six donors to find two O* donor in the 6th donor of the day? (a) 0.3292 (b) 0.0329 (c) 0.1097 (d) 0.1314

Assume that when human resource managers are randomly selected, 46% say job applicants should follow up within two weeks. If 13 human resource managers are randomly selected, find the probability that fewer than 3 of them say job applicants should follow up within two weeks. The probability is (Round to four decimal places as needed.)

In a recent​ year, a hospital had 4275 births. Find the mean number of births per​ day, then use that result and the Poisson distribution to find the probability that in a​ day, there are 13 births. Does it appear likely that on any given​ day, there will be exactly 13 ​births? 1) The mean number of births per day is ......? 2) The probability​ that, in a​ day, there are13 births is....?

In a 24-hour call center, complaints arrive at a mean rate of 1 complaint every 3 hours. (a) Find the probability that there are at most 3 complaints in the past 10 hours. (b) A day is “doomed” if there are at least 6 complaints. Each day, an inspector counts the number of complaints at the end of the day and determines whether the day was doomed. Find the probability that the inspector has worked for 7 days when he records the 3rd doomed day. (c)  Find the probability that there are at least 2 complaints in the past 12 hours given that there are at most 5 complaints in the past 12 hours

how do i solve parts A and B?

In a recent​ year, an author wrote178checks. Use the Poisson distribution to find the probability​ that, on a randomly selected​ day, he wrote at least one check what is the probability  SHARE
