Suppose that on an average two tornadoes occur in 10 years in a county in Oklahoma. Further assume that the tornado-generated wind speed can be modeled by a log-normal random variable with a mean of 120 mph and a standard deviation of 12 mph. (a) What is the probability that there will be at least one tornado next year? (b) If a structure in the county is designed for wind speed of 150 mph, what is the probability that the structure will be damaged during such a tornado? (c) What is the probability that the structure will be damaged by tornado next year? (Hint: consider that any number of tornadoes can occur next year)

Each of the batteries in a collection of 40 batteries is equally likely to be either a type A or a type B battery. Type A batteries last for an amount of time that has mean 50 and standard deviation 15; type B batteries last for an amount of time that has mean 30 and standard deviation 6. (a) Approximate the probability that the total life of all 40 batteries exceeds 1700. (b) Suppose it is known that 20 of the batteries are type A and 20 are type B. Now approximate the probability that the total life of all 40 batteries exceeds 1700.

A supervisor at a local widget making company has been monitoring the output of one of the machines used to manufacture small aluminum plates. Past data indicate that if the machine is operating "properly," the length of the plates produced by this machine can be modeled as being normally distributed with a mean of 117 centimeters and a standard deviation of 5.2 centimeters. Suppose 16 plates produced by this machine are randomly selected. What is the probability that the average length of these 16 plates will be between 116 and 120 centimeters when the machine is operating "properly?" Z and t TABLES ARE GIVEN AS QUESTIONS 28-29.
