Exercise 4: Traffic Fatalities and Intoxication. The National Safety Council publishes information..
  Exercise 4: Traffic Fatalities and Intoxication. The National Safety Council publishes information about automobile accidents in Accident Facts. According to that document, the probability is 0.35 that a traffic fatality will involve an intoxicated or alcohol-impaired driver or nonoccupant. In eight traffic fatalities, find the probability that the number, Y, that involve an intoxicated or alcohol-impaired driver or nonoccupant is a) exactly three; b) between two and four, inclusive. c) Find and interpret the mean of the random variable Y. d) Obtain the standard deviation of Y. Exercise 5: The shell of the land snail Limocolaria martensiana has two possible color forms: streaked and pallid. In a certain population of these snails, 60% of the individuals have streaked shells. Suppose that a random sample of 10 snails is to be chosen from this population. Find the probability that the number of streaked-shelled snails in the sample will be a) exactly 5 b) exactly 6 c) between 4 and 7, inclusive. Exercise 6: Childhood lead poisoning is a public health concern. In a certain population, 1 child in 8 has a high blood lead level (defined as 30 mg/dl or more). In a randomly chosen group of n = 16 children from the population, what is the probability that a) b) c) none of the children has high blood lead? 1 child has high blood lead? at least 2 children have high blood lead?
