Five observations taken for two variables follow. 3. Which of the following scatter diagrams accurately represents the data set? A. - Select your answer - v b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? - Select your answer - v c. Compute the sample covariance (to 1 decimal and enter negative value as negative gure). 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
