4. From a sample of the 2008 ANES data, you have the following information on race and party ID. Dem. Ind. Rep. Total White, non-Hispanic 543 152 620 Black, non-Hispanic 105 17 5 Hispanic 57 11 22 Other, non-Hispanic 27 13 21 Total (a) Calculate the marginal probabilities for race and party ID. (b) Use the marginal probabilities and the total number of respondents to calculate the expected number of entries in each cell, under the null hypothesis of independence. (c) Use the expected and observed cell counts to calculate the chi squared (x) statistic. Would we reject the null hypothesis of independence at the 5% level? 4.
