1. Define the range, variance, and standard deviation for a population.
2. Discuss how the variance and the standard deviation measure variation.
3. The Empirical Rule for a normally distributed population and Chebyshev's Theorem have the same basic purpose. In your own words, explain what this purpose is.
METHODS AND APPLICATIONS
4. Consider the following population of five numbers: 5, 8, 10, 12, 15. Calculate the range, variance, and standard deviation of this population.
