The new proportion of to the proportion that actually voted. eTextbook and Media is !!! ***
(b) What is the standard deviation of sample proportions when you take samples of 2,216 from the population of all eligible voters, where the proportion that voted in the population is 0.592? Round answer to 4 decimal places, e.g. 0.2358. SD of sample proportions is i eTextbook and Media How many standard deviations is the sample proportion of 1,523/2,216 above 0.592? Round answer to 2 decimal places, e.g. 0.23. The sample proportion of 1,523/2,216 is eTextbook and Media standard deviations above 0.592.
(d) Is the General Social Survey (GSS) result still significantly larger than the actual result? Choose the best among the following statements. Because the sample proportion is Results like this are very eTextbook and Media 0.592, it ✓to happen by chance. significantly larger than the actual result.
