?In politics, marketing, etc. we often 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 $76\%(72\%$ ?minus $4\%$ ?to $72\%$ ?plus $4\%).$

In a $($made$-$up$)$ ?poll, the proportion of people who like dark chocolate more than milk chocolate was

$26\%$ ?with a margin of error of $1\mathrm{.}3\%.$ ?Describe the conclusion about $p$ ?using an absolute value

inequality.

The answer field below uses the symbolic entry option in Mobius. That lets you type in a vertical bar I to

represent absolute values. Also, when you type in $$ ?and then $=,$ ?the symbolic entry option will

automatically convert that to $?.$ ?In the same way, if you type in $>$ ?and then $=,$ ?the symbolic entry

option will automatically convert that to $?.$

Be sure to use decimal numbers in your answer $($such as using $0\mathrm{.}40$ ?for $40\%).$
