On a planet of Mercury 4 year olds average 3 hours a day unsupervised.Most of the unsupervised children live in rural areas,considered safe.Suppose that the standard deviation is 1.6 hours and the amount of time spent alone is normally distributed.We randomly survey one Mercurian 4 year old living in a rural area.We are interested in the amount of time X the child spends alone per day.Round all answers 4 decimal places where possible. Find the probability that the child spends less than 2.5 hours per day unsupervised What percent of the children spend over 2.9 hrs per day unsupervised round 2 decimal places 65% of all children spend at least how many hours per day unsupervised?
