In politics, marketing, etc. we oen want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and T6% (?2% minus 4% to ?2% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 45% with a margln of error of 1.5%. Describe the conclusion about p using an absolute value inequality. The answer eld below uses the symbolic entry option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in and then 2, the symbolic entry option will automatically convert that to 2*. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%). ab Sin (a)
