Find the indicated mean. The mean number of homicides per year in one city is 21.4. Suppose a Poisson distribution will be used to find the probability that on a given day there will be fewer than 4 homicides. Find the mean of the appropriate Poisson distribution (the mean number of homicides per day). Round your answer to four decimal places. 21.4 0.412 5.35 0.0586

Step 1
Given mean number of homicides per year = 21.4 Mean number of homicides per day = 21.4 / 365 = 0.0586 (rounded to four decimal places) Show more…

Data from 14 cities were combined for a 20-year period, and the total 280 city-years included a total of 153 homicides. After finding the mean number of homicides per city-year, find the probability that a randomly selected city-year has the following numbers of homicides, then compare the actual results to those expected by using the Poisson probabilities: Homicides each city-year a. 0 b. 1 c. 2 d. 3 e. 4 Actual results 162 89 24 4 1 a. P(0)= P(1)= P(2)= P(3)= P(4)= (Round to four decimal places as needed.)

Use the fact that the variance of a Poisson distribution is $\sigma^{2}=\mu$. The mean number of bankruptcies filed per hour by businesses in the United States in a recent year was about five. (a) Find the variance and the standard deviation. Interpret the results. (b) Find the probability that at most three businesses will file bankruptcy in any given hour.
