A researcher times rats in running a maze and finds that the average time for all of the rats to complete the maze is 34 seconds. She then breeds only those rats that ran the maze in 25 seconds or less and finds that the rats in generation two complete the maze in an average of 28 seconds. If the mean time of the breeding rats from generation one was 21 seconds, what is the heritability of maze running?
