A normally distributed data set has a mean of 0 and a standard deviation of 2. The closest to the percent of values between -4.0 and 2.0 would be 84%.
<h3>What is the empirical rule?</h3>
According to the empirical rule, also known as the 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95%, and 99.7% of the values lies within one, two, or three standard deviations of the mean of the distribution.

A normally distributed data set has a mean of 0 and a standard deviation of 2.

Answer:
see explanation
Step-by-step explanation:
given
a² + b² = c² ( isolate b² by subtracting a² from both sides )
b² = c² - a² ( take the square root of both sides )
= ± 
b = ±

Answer:
m = 3.86
Step-by-step explanation:
