About what percent of values lie between the second and third standard deviations (both sides)?
Approximately of values lies between the second and third standard deviation
The empirical rule additionally alluded to as the three-sigma rule or 68-95-99.7 rule, is a factual decision that expresses that for a normal distribution, practically totally noticed information will fall inside three standard deviations of the mean or normal .
The Empirical Rule expresses that of information noticed observing an normal distribution exists in standard deviations of the mean. Under this standard, of the information falls inside one standard deviation, percent inside two standard deviations, and inside three standard deviations from the mean.
Therefore, the percentage of values from normal distribution lie between second and third standard deviation will be:

a. I only
b. II only
c. III only
