Question

im given the mean of 42 months and standard deviation of 10 months.  Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the prison terms actually served lie between _____ months and _____ months.

anonymous · Answer

The empirical rule says approximately 68% of the distribution lies within one standard deviation of the mean. That is, 68% lies between (mean + std dev) and (mean - std dev). In this case, the mean is 42 and the standard deviation is 10.
