Empirical Rule
Instructions: Use the empirical rule to find the following probabilities.
Remember to draw a normal curve, label the r-values for 1, 2, and 3 standard
deviations from the mean, and write in the probabilities between each
standard deviation before answering the questions.
On average, Upstate Chevrolet sells 20 cars each week, with a standard
deviation of 2.
