Simple: 160 divided by 32 = the answer which is about 3% (exactly 3.3125)
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:



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:

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).
