Answer 1

Answer:

The correct option is (d) 21.19%.

Step-by-step explanation:

Let the random variable X denote the heights of Fernando's peers.

The mean and standard deviation of the random variable X are:

μ = 68 inches

σ = 10 inches

It is provided that Fernando is 60 inches tall.

Compute the value of P (X < 60) as follows:

$P(X$

                  $=P(Z$

*Use a z-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).
