Using the empirical rule, you would expect 95 percent of the values to be within two standard deviations of the mean. Using the formula for the standard deviation is for a sample sum: so you would expect 95 percent of the values to be between 5,000 + (2) (44.3) and 5,000 – (2) (44.3), or between 4,911.4 and 588.6. 86.Statistics starts from data and then asks what was used to generate it.
