5. The number of accidents per week at a hazardous intersection varies with mean 2.2 and standard deviation 1.4. This distribution takes only whole-number values so is certainly not Normal. (a) Let x be the mean number of accidents per week during a year. What is the approximate distribution of x according to the Central Limit Theorem? (b) What is the approximate probability that x is less than 2? [2, 10.27]
