According to San Jose Mercury News, children in China average 3 hours a day unsupervised. Most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1 hours and the amount of time spent alone is normally distributed. We randomly survey one Chinese child living in a rural area. 1. Find the probability that the child spends more than 5 hour per day unsupervised. 2. What percent of the children spend less than 2 hours per day unsupervised? We randomly survey 100 Chinese children living in a rural area. 1. What is the chance that the average of unsupervised hour for these 100 children is less than 2.9? 2. What is the chance that the sample average of unsupervised hour for these 100 children is between 2.8 and 3.2 hours?
