Select True or False from each pull-down menu, depending on whether the corresponding statement is true or false.

? True False  1. Chebyshev's theorem states that the percentage of observations in a data set that should fall within five standard deviations of the mean is at least 96%.

? True False  2. The Empirical Rule states that the percentage of observations in a data set (providing that the data set has a bell shaped and symmetric distribution) that fall within one standard deviation of the mean is approximately 75%.

? True False  3. While Chebyshev's theorem applies to any distribution, regardless of shape, the Empirical Rule applies only to distributions that are bell shaped and symmetrical.

? True False  4. The mean of fifty sales receipts is 66.75 and the standard deviation is 10.55. Using Chebyshev's theorem, at least 75% of the sales receipts were between 45.65 and 87.85
