In a normal distribution, if x bar represents the mean and o represents the standard deviation what percent of information falls between x bar and x bar + o?
a. 34
b. 50
c. 68
d. 95
Homework Answers
By the empirical rule, 68% of the data lies between 1 standard deviations from the mean i.e. between x bar - o and x bar + o.
Hence,
Percent of information falls between x bar and x bar + o
= 68% /2
= 34%
Option A is correct.
