3) At a recent PTA meeting, Mrs. Anderson voiced a complaint that the school children spend too much time on school buses, and she demanded that more buses and shorter routes be provided. The representative from the Board of Education responded that, on the average, a school child spends only 30 minutes per day on the bus. Mrs. Anderson promptly retained you to conduct an investigation of her claim. You then selected 10 names at random from the student body and had those students keep careful records of the amount of time they spent on the bus on a randomly selected day in a randomly selected week in April. The scores are given below.
