Five observations taken for two variables follow. a. Which of the following scatter diagrams accurately represents the data set? b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? c. Compute the sample covariance (to 1 decimal and enter negative value as negative figure), Interpret the sample covariance. b. What does the scatter diagram developed in part \( (a) \) indicate about the relationship between the two variables? c. Compute the sample covariance (to 1 decimal and enter negative value as negative figure). In rammat tha sample covariance. d. Compute the sample correlation coefficient (to 3 decimals and enter negative vanue as negative figure).
