Ch9: Problem 2 Previous Problem Problem List Next Problem (6 points) A linear regression is performed with variables x and y, resulting in sample correlation of -0.466. Suppose that this is based on 24 data pairs. You are Interesting in determining if there is a negative linear relationship between x and y in the population and will determine this by performing a test of the population correlation Fill in the blank with the test value Hip D What sign should appear in the alternative hypothesis? OA OB The test statistic for this test is The p-value for this test is Select the appropriate conclusion for this test at a significance level of a 0,05 O A. Reject H. We have significant evidence that there is a negative linear relationship between x and y in the population OB. Fail to reject Ho. We do not have significant evidence that there is a negative linear relationship between x and y in the population What is the coefficient of determination for this sample?
