A random sample of 680 viewers was selectedand asked to watch the first two episodes. After viewing the episodes, 425 viewers indicated they would watch the new series.(Round your answers to 3 decimal places.)a. Find the value of the sample proportion of people who would watch the new series.Sample proportion0.625b.

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 39% with a margin of error of 1.3%. 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 | 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 0.40 for 40%).
The 2004 General Social Survey asked a random sample of 977 adult Americans how often they feel rushed, with three options to choose from: always, sometimes, and never. The sample result was that 304 of the 977 people responded "always." Calculate the value of the test statistic by hand. Round the sample proportion and the hypothesized value of the proportion to THREE decimal places. Round the final answer to TWO decimal places.
