A measure of brain activity (called median power frequency, or MPF in Hz) was recorded at the same location in the brain both before and after the diesel exhaust exposure. The resulting data are given in the accompanying table. For purposes of this exercise, assume that the sample of 10 men is representative of healthy adult males.
