According to the National Survey of Student Engagement, the average student spends about 17 hours each week preparing for classes; preparation for classes includes homework, reading and any other assignments. (Data extracted from "How much do you study...") Assume the standard deviation of time spend preparing for classes is 4 hours. If you select a random sample of 16 students, If you select a random sample of 64 students, there is an 85% chance that the sample mean is less than how many hours per week?
