The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 44 and a standard deviation of 7. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 37 and 44? ans = %

ans = %
Given:
The distribution of the number of daily requests is bell-shaped and has a mean of 44 and a standard deviation of 7.
Mean,
Standard deviation,
The empirical rule states that:
According to the Empirical rule, 68% of the data falls within one standard deviation, 95% falls within two standard deviations and 99.7% within three standard deviations from the mean.
