The number of accidents per week at a hazardous intersection varies with mean 2.0 and standard deviation 1.2. this distribution takes only whole-number values, so it is certainly not normal. (a) let x be the mean number of accidents per week at the intersection during a year (52 weeks). what is the approximate distribution of x according to the central limit theorem? μx = σx = (b) what is the approximate probability that x is less than 2? (c) what is the approximate probability that there are fewer than 120 accidents at the intersection in a year? (hint: restate this event in terms of x.)
