The physical plant at the main campus of a large state university receives daily requests to replace fluorescent light bulbs. the distribution of the number of daily requests is bell-shaped and has a mean of 49 and a standard deviation of 10. Using the empirical rule, what is the approximate percentage of lightbulb replacement requests numbering between 49 and 79?
