So we know what this area is, the area within two standard deviations. The empirical rule tells us. Or even better, the 68, 95, 99.7 rule tells us that this area-- because it's within two standard deviations-- is 95%, or 0.95. Or it's 95% of the area under the normal distribution.
13.10.2020 · So the 68% is a subset of 95%. And I think you know where this is going. If we go three standard deviations below the mean and above the mean, the empirical rule, or the 68, 95, 99.7 rule tells us that there is …
