For drivers in the 20-24 age bracket, there is a 34% rate of car accidents in one year (based on data from the National Safety Council.) An insurance investigator finds that in a group of 500 randomly selected drivers aged 20-24 living in a certain city, 40% of them had accidents in the last year. Assuming that the 34% rate applies to aged 20-24 living in that certain city, find the mean and standard deviation for the numbers of people in groups of 500 that can be expected to have accidents.
