n30of 42 Step 4 of 5 A sample of 92 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 $90 and the standard deviation is $13. One motel charged $64 per night which is the 13h percentile. Another motel charged $122 per night which is the 75"h percentile Step 4 of S: If the z-šcore for a motel is -0.6, what is the price of a single room at the motel (in dollars)? 2 Points Keypad Tables Prev Next

Explanation / Answer

Z = (x - mean)/SD

Or, -0.6 = (x - 90)/13

Or, x - 90 = -0.6 * 13

Or, x = -7.8 + 90

Or, x = 82.2

SO the price of the single room is 82.2
