The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Suppose the number of tickets written per day follows a Poisson distribution with a mean of 6 tickets per day. Find the probability that exactly 7 tickets are written on a randomly selected day from this distribution.

6. A certain typing agency employs 3 typists. The average number of errors per article is 2.2 when typed by the first typist, 2.7 when typed by the second, and 3.1 when typed by the third. If your article is equally likely to be typed by any of the three typists, approximate the probability that it will have no errors. Again assume that for each typist the number of errors follows a Poisson distribution.

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 1.70 accidents per day on this section of the interstate. Let r be a random variable that represents number of accidents per day. Let O 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...

Huang’s television-repair service receives an average of 9 TV sets per 6-hour day to be repaired. The service manager would like to be able to tell customers that they can expect their TV back in 4 days. What average repair time per set will the repair shop have to achieve to provide 4-day service on the average? (Assume that the arrival rate is Poisson distributed and repair times are exponentially distributed.) (Round answer to 2 decimal places, e.g. 2.75.) Average...
