18. In a certain factory manufacturing razor blades, there is a small1chance, for any blade to be defective. The blades are placed in50packets, each containing 10 blades. Using the Poisson distribution,calculate the approximate number of packets containing not morethan 2 defective blades in a consignment of 10000 packets.

2) The average number of operational losses a year at a particular plant is 18, so the number of losses in a year is distributed Poisson, with a mean 18. a. Using the probability distribution formula for the Poisson distribution, What is the probability that there will exactly 12 operational losses in the next year ? b. Using the table lookup method, what is the probability of having less than three operational losses in one month ? 3) Given the distribution parameter from the previous question: a. What is the average number of weeks between operational losses ( assume 52 weeks per year ) ? b. What is the probability that two operational losses will occur within two weeks of each other ?

Three randomly selected households are surveyed. The numbers of people in the households are 2 , 7 , and 12 . Assume that samples of size nequals 2 are randomly selected with replacement from the population of 2 , 7 , and 12 . Construct a probability distribution table that describes the sampling distribution of the proportion of even numbers when samples of sizes nequals 2 are randomly selected. Does the mean of the sample proportions equal the proportion of even numbers in the population? Do the sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples. 2 ,2 2 ,7 2 ,12 7 ,2 7 ,7 7 ,12 12 ,2 12 ,7 12 ,12
On average, there is one hurricane in the Bahamas every year. The cost torepair the damage of each hurricane in the Bahamas to a particular resort is 100. To stabilizefinances, the resort buys hurricane insurance, which will cover the cost of the repairs foreach hurricane after the second. Assume that the number of hurricanes in the Bahamas ina given year is Poisson distributed. 1. What is the expected cost of repairs in a given year to the resort (not including thecost of insurance)?2. What is the expected payout of the insurance company on the resort’s policy in agiven year?
