A sample of 104 motels is selected from a large urban area and the price for a night of lodging for a single room was determined for each motel. The mean rate is computed to be $100 and the standard deviation is $13. One motel charged $68 per night which is the 13th percentile. Another motel charged $120 per night which is the 75th percentile.   Step 4 of 4 :   How many motels charged between $68 and $120? Round your answer to the nearest integer.
