6.3 Working with Normally Distributed Variables ?
? ? As illustrated in the previous example,the 68.26-95.44-99.74 rule allows us to?obtain useful information about a normally distributed variable quickly and easily Experience has shown that the 68.26-95.44-99.74 rule works reasonably well for?any variable having approximately a bell-shaped distribution,regardless of whether?the variable is normally distributed. This fact is referred to as the empirical rule,该法则适用于形状似钟的分布，有时可能该分布不是正态分布。 ?
