\\I a A civil engineer has been studying the frequency of vehicle accidents on a certain stretch of interstate highway. Longterm history indicates that there has been an average of 1.78 accidents per day on this section of the interstate. Let r be a random variable that represents number of accidents per day. Let 0 represent the number of observed accidents per day based on local highway patrol reports. A random sample of 90 days gave the following information. r 0 1 2 3 4 or more 0 21 22 15 18 14 (a) The civil engineer wants to use a Poisson distribution to represent the probability of r, the number of accidents per day. The Poisson distribution is given below. e71 )lr r! Here A = 1.78 is the average number of accidents per day. Compute PM for r = O, 1, 2, 3, and 4 or more.
