The distribution of heights for adult men in a certain population is approximately normal with mean 70 inches and standard devia
Allisa [31]

Answer:

The correct option is (C).

Step-by-step explanation:

Let <em>X</em> = heights for adult men in a certain population.

The random variable <em>X</em> follows a Normal distribution with mean <em>μ</em> = 70 inches and standard deviation, <em>σ</em> = 4 inches.

Compute the heights that represents the middle 80 percent of the heights as follows:

P(x_{1}

P(\frac{x_{1}-\mu}{\sigma}

P(-z

The value of <em>z</em> for the probability P (Z < <em>z</em>) = 0.90 is,

<em>z</em> = 1.282

*Use a <em>z</em>-table.

Compute the two heights as follows:

-1.28=\frac{x_{1}-70}{4}\\x_{1}=70-(1.282\times 4)\\x_{1}=64.872\\x_{1}\approx 64.87                1.28=\frac{x_{2}-70}{4}\\x_{2}=70+(1.282\times 4)\\x_{2}=75.128\\x_{2}\approx 75.13

Thus, the two heights which represents the middle 80 percent of the heights are 64.87 inches and 75.13 inches.

The correct option is (C).
