Expert Solution

Step 1

To answer the above question first we need to know about the empirical rule.

The Empirical rule, also known as 3 sigma rule or 68-95-99.7 rule predicts that for a normal distribution 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ). Where µ is the mean and σ is the standard deviation of the distribution.
