In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is t
aksik [14]

The absolute value inequality is given as |(p - 0.43)I ≤ 0.019

<h3 />

<h3>How to describe the proportion using the absolute value inequality</h3>

The proportion p = 43% = 0.43

Margin of error = 1.9% = 0.019

The value of the proportion can then be said to lie between

(0.43 - 0.019) ≤ p ≤ (0.43 + 0.019)

In order to convert to the absolute inequality we would be having

-0.019 ≤ (p - 0.43) ≤ 0.019

I (p - 0.43)I ≤ 0.019
