What is the proportion of variability in the percentage of votes for Al Gore that can be explained by the linear relationship to the percentage ofAfrican American county residents?4. What is the expected value of the percentage of votes for Al Gore when the percentage of African American county residents is 0?5 What is the standard error value you would use to construct a confidence interval for the slope, B1?6. Calculate a 95% confidence interval for the slope, B1. 8. Based on the p-value reported on the computer output, we have Extremely Strongv evidence that there isv a linear relationshipbetween the percentage of African American county residents and the percentage of votes for Al Gore.9. 16.0181% of the residents of one county were African American.

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
