The correct option is (d) 21.19%.

Let the random variable <em>X</em> denote the heights of Fernando's peers.
The mean and standard deviation of the random variable <em>X</em> are:
<em>μ</em> = 68 inches
<em>σ</em> = 10 inches
It is provided that Fernando is 60 inches tall.
Compute the value of P (X < 60) as follows:
*Use a <em>z</em>-table.
The percentage is, 0.2119 × 100 = 21.19%.
Thus, the percentage of his peers are shorter than Fernando is 21.19%.
The correct option is (d).
