"Because the digits 0, 1, 2, . . . . 9 are the normal results from lottery drawings, such randomly selected numbers have a normal distribution." 1-3. Collecting Sample Data 25 2. Normal Distribution A normal distribution is informally described as a probability dis- Textbook tribution that is "bell-shaped" when graphed.
