- Select your answer - c. Compute the sample covariance (to 1 decimal and enter negative value as negative figure). Interpret the sample covariance. Select your answer - d. Compute the sample correlation coefficient (to 3 decimals and enter negative value as negative figure). Interpret the sample correlation coefficient. Hint: If the correlation coefficient is greater than 0.80 or less than -0.80, there is a strong relationship. Select your answer -
