In a given population,11% of the likely voters are African American

1. In a given population,11% of the likely voters are African American. A survey using a simple random sample of 600 landline telephone numbers finds 8% African Americans. Is there evidence that the survey is biased? Explain.

2. A new version of the SAT test is given to 1000 randomly selected high school seniors. The sample mean test score is 1110, and the sample standard deviation is 123. Construct a 95% confidence interval for the population mean test score for high school seniors.
