1. According to a recent Newsweek poll, 64% of Americans oppose a constitutional amendment to allow a US citizen born in another country, like Schwarzennegger, to be elected president. This was based on a poll of 1004 adults. Model the distribution of the sample proportion of American adults who oppose the amendment. Simulate 200 samples with a sample size of n=1004. http://www.msnbc.com/news/978672.asp?0cv=CB20
1. Give a graphical summary of the samples.
2. Compare your results to the sampling distribution model for a proportion given on page 340.
2. Create a probability distribution. Take 200 samples of size 500 from your distribution and find the mean of each sample.
1. Find the mean, variance, and standard deviation for your distribution using formulas from chapter 16.
2. Find the mean, variance, and standard deviation for the mean of your 200 samples.
3. Compare your results to the Central Limit Theorem on page 345.
3. Use the 2000 General Social Survey to gather information and then the claim that 1/3 of 18-24 year-olds think Marijuana should be legal.
4. Use the 2000 General Social Survey to determine if the proportion of black males and black females who feel a racist should be allowed to speak are the same.
