1. The number of surface flaws in plastic panels used in the interior of automobiles has a Poisson distribution with a mean of 0.06 flaws per square foot of plastic panel. Assume automobile interior contains 10 square feet of plastic panel.

(a) What is the probability that there are no surface flaws in an auto?s interior?

(b) If 10 cars are sold to a rental company, what is the probability that none of the 10 cars has any surface flaws?

(c) If 10 cars are sold to a rental company, what is the probability that at most two cars have any surface flaws?

2. The article ?Determination of Carboxyhemoglobin Levels and Health Effects on Officers Working at the Istanbul Bosporus Bridge? (G. Kocasoy and H. Yalin, Journal of Environmental Science and Health, 2004: 1129-1139) presents assessments of health outcomes of people working in an environment with high levels of carbon monoxide (CO). Following are the numbers of workers reporting various symptoms, categorized by work shift.

Can we conclude that the proportions of workers with various symptoms differ among the shifts? Use ? = 0.10
