A normal distribution is symmetrical about the mean. Therefore half of all young men are shorter than 68 inches.

The given says the height distribution is normally distributed with the mean height equal to 68 inches. In this case, the bell-shaped curve has a vertical symmetry at 68 inches. This means, half of the mean exceeds 68 inches while the other half has height below 68 inches.
