In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin or error- the largest (reasonable) 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 44% with a margin of error of 1.3%. Describe the conclusion about p using an absolute value inequality.

If the proportion of Hs is .45 out of 200 flips, what is the p-value?

A story describing a burger taste test among non-vegetarians was read by 352 high school students. To investigate the effect of the type of burger (veggie or meat) on subject's opinion of whether or not the burger tasted good, each burger had labels of veggie burger, beef burger, or a burger with no label. Each person was asked whether the burger tasted was good or not. Data are given in the accompanying table. Is there evidence that the proportion who believe that the burger tasted good for the three different labels differ? Test the relevant hypotheses using ? = 0.01. (Round your answer to two decimal places.)
