Question

Question 27 In 1898 L. J. Bortkiewicz published a book entitled The Law of Small Numbers. He used data collected over 20 years to show that the number of soldiers killed by horse kicks each year in each corps in the Prussian cavalry followed a Poisson distribution with a mean of 0.63. (a) What is the probability of one or more deaths in a corps in a year? (b) What is the probability of no deaths in a corps over 4 years? Round your answers to four decimal places (e.g. 98.7654) (a) The probability is (b) The probability is

    Any help? 2. The Prussian horse-kick data: The derivation of the Poisson distribution that we did in class is due to Poisson. However, this distribution did not see much application until a text by Bortkiewicz in 1898. One famous example from that text is the use of the “Prussian horse-kick data" to illustrate how the Poisson distribution may help evaluate whether rare events are really occurring independently or randomly. Bortkiewicz studied the distribution of 122 men kicked to death by...

Let r be a discrete random variable that can take the values 0, 1,2,... A quantity r is said to be Poisson distributed if the probability P(x) of obtaining z is tivated Poisson, was connected with the rare event of someone being kicked to death by a horse in the Prussian army. The number of horse-kick deaths of...
