Does more education lower a person’s level of prejudice? The number of years of education and the score on a prejudice test for ten people is given in the following table. Higher scores on the test indicate more prejudice.   Years of Education: 12, 15, 14, 13, 18, 10, 16, 12, 10, 4 Score of Prejudice Test: 1, 6, 2, 3, 2, 4, 1, 5, 5, 10   Conduct a hypothesis test to determine if there is a significant linear correlation between the two variables. If there is a significant linear correlation between the variables, determine the regression equation.  There is a significant correlation between the variables and the regression equation is y' = 10.5 - 0.532x  There is a significant correlation between the variables and the regression equation is y' = - 0.532 + 10.5x  There is not a significant correlation between the variables, so the regression equation should not be determined.  There is a significant correlation between the variables and the regression equation is y' = 16.509 - 1.054x

In Exercises 5–18, test the given claim. Tennis Challenges The table below shows results since 2006 of challenged referee calls in the U.S. Open. Use a 0.05 significance level to test the claim that the gender of the tennis player is independent of whether the call is overturned. Do players of either gender appear to be better at challenging calls?

Conduct an hypothesis testing using a 5% significance level Using P value or classical approach. Determine whether votes for governor in a particular election are independent of the voter's political party affiliation.
