The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 65 and a standard deviation of 9. Using the 68-95-99.7 (Empirical) Rule, what is the approximate percentage of lightbulb replacement requests numbering between 56 and 65? The approximate percentage of lightbulb replacement requests numbering between 56 and 65 is \( \square \) \%. (Do not enter the percent symbol.) Question Help: Video Post to forum Submit Question
