The physical plant at the main campus of a large state university receives daily requests to replace florescent light bulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 45 and a standard deviation of 4. Using the empirical (68-95-99.7) rule, what is the approximate percentage of light bulb replacement requests numbering between 37 and 45? Do not enter the percent symbol.  Caution: Using tables or Excel for this may produce a wrong answer. Use the 68-95-99.7 rule. Answer =  % (Enter your answer as a percent, but do not enter the percent symbol. Do not enter in decimal form or round your answer. For example, enter 93.8 for 93.8%, not 0.939)
