The purpose of this activity is to learn how to use the calculator to compute probabilities and values for the normal distribution. zZZZ Do we humans get enough amount of sleep we need? While amount or quality of sleep undergoes a wide variety of changes during the human life span (based primarily upon age and life style), the amount of sleep, at any given age, has a relatively normal, bell-shaped distribution. We will use this information to explore your sleep habits. First you need to collect a small data set. Each team member will record, to the nearest quarter of an hour, how many hours s/he slept in the past 24 hours. If you are not working with your group then survey some of your friends or family members. Name Hours
