To estimate the heritability of maze-learning ability in rats, a selection experiment was carried out. From a population in which the average number of trials necessary to learn the maze was 10.8. Animals were selected that managed to learn the maze in an average of 5.8 trials. Their offspring required an average of 8.8 trails to learn the maze. Calculate the narrow-sense heritability of maze-learning ability in this population.
