Using the Empirical Rule, approximately what percentage of the incomes lie between 2 and +2 ? 2. It's known that 68% of the incomes lie between $40,000 and $60,000. Can we determine the values of and based on this information? If so, how? 3. An analyst claims that only 80% of the incomes fall within two standard deviations of the mean for this population.
