1. A normal distribution is informally described as a probability distribution that is "bell-shaped" when graphed. Draw a rough sketch of a curve having the bell shape that is characteristic of a normal distribution. 2. Identify the two requirements necessary for a normal distribution to be a standard normal distribution.
