A company publishes statistics concerning car quality The initial quality score measures the number of problems per new car sold For one year, Car A had 1 15 problems per car. Let the random variable X be equal to the number of problems with a newly purchased model A car. Complete parts (a) through (d). a. What assumptions must be made in order for X to be distributed as a Poisson random variable? Select all the assumptions for a Poisson distribution. A. At least 30 model A cars are sold. LY B. The probability of a problem in a time period approaches zero as the length of the time period becomes smaller. LY C. The number of problems in a given period is independent of the number of problems in any other period D. The probability of a problem is the same for each period of time. b. Making the assumptions as in (a), if you purchased a model A car, what is the probability that the new car will have zero problems? The probability that the new model A car will have zero problems is]. (Round to four decimal places as needed.)
