Refer to the following scenario. A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs should be located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 124 people living in Gastown and finds that 20 have an annual income that is below the poverty line. Suppose that the government official wants to re-estimate the population proportion and wishes for his 90% confidence interval to have a margin of error no larger than 0.04. How large a sample should he take to achieve this? Please carry answers to at least six decimal places in intermediate steps, and use at least 3 decimal places in your critical value. Sample size =
Polling 2004. In the 2004 U.S. presidential election,the official results showed that George W. Bush received50.7% of the vote and John Kerry received 48.3%.

Suppose you had taken a random sample of 1000voters in an exit poll and asked them for whom they hadvoted.a) Would you always get 507 votes for Bush and 483 forKerry? b) In 95% of such polls, your sample proportion of vot-ers for Bush should be between what two values? c) In 95% of such polls, your sample proportion of vot-ers for Nader should be between what two numbers? d) Would you expect the sample proportion of Nadervotes to vary more, less, or about the same as thesample proportion of Bush votes?

Four Quarters the Same as $1? In a study of the “denomination effect,” 43 college students were each given one dollar in the form of four quarters, while 46 other college students were each given one dollar in the form of a dollar bill. All of the students were then given two choices: (1) keep the money; (2) spend the money on gum. The results are given in the accompanying table (based on “The Denomination Effect,” by Priya Raghubir and Joydeep Srivastava, Journal of Consumer Research, Vol. 36.) Use a 0.05 significance level to test the claim that whether students purchased gum or kept the money is independent of whether they were given four quarters or a $1 bill. Is there a “denomination effect”?
Researchers want to determine whether all bags of M&M's® have the same proportion of colors regardless of the flavor of M&M's®. To test this, they sampled randomly king-size bags of each flavor and recorded their findings in the table. Part A: What are the correct degrees of freedom for this table? Part B: Calculate the expected count for the number of green peanut M&M's®. Show your work. Part C: Is there sufficient evidence that there is a difference in the proportion of colors for the different flavors of M&M's®? Provide a statistical justification for your conclusion.
In a US presidential election, the incumbent president wins with 51.5% of the vote to 48.2% for the primary challenger (and .3% to others). In a nationwide telephone poll of 1000 people conducted exactly one week before the election by a university polling group, 49% of people polled supported the incumbent president, 50% supported the challenger, and 1% supported other candidates. a. For the polling study, what was the population of interest? b. What was the sample? c. Why did the sample results differ from the population? d. What are two constants that might have limited the generalizability of the polling results?
