20. Using a Z-score table. Fernando is 60 inches tall. The
average height for his age and gender is 68 with a standard
deviation of 10 inches. What percent of his peers are
shorter than him?
a) 46.81%
b) 8%
c) 78.81%
d) 21.19%

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:

*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).

answer: finding the extract measurements and knowing the points

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
