Suppose 4-year-olds in a certain country average3hours a day unsupervised and that most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is1.8hours and the amount of time spent alone is normally distributed. We randomly survey one 4-year-old living in a rural area. We are interested in the amount of time the child spends alone per day.
