The physical plant at the main campus of a large state university receives daily requests to replace fluorescent lightbulbs. The distribution of the number of daily requests is bell shaped and has a mean of 35 and a standard deviation of 10. Using the empirical rule, what is the approximate percentage of light bulb replacement requests numbering between 25 and 35?
