The sample covariance between x and z is V . The sample correlation coefcient between x and 2 is Y . Select the best conclusion based on your calculations of the preceding correlation coefcients. If} The calculations show a positive linear relationship between x and yr a negative linear relationship between v and z. and a negative linear relationship between x and z. " J The calculations show a negative linear relationship between x and v, a positive linear relationship between v and z, and no relationship between x and 2. If} The calculations show a negative relationship between x and v, a positive relationship between v and z, and a negative relationship between x and 2. '35 The calculations show no linear relationship between x and v. a negative linear relationship between v and z, and a strong negative linear relationship between x and 2
