Question

The following is a random sample of eleven (x,y) pairs

a. Compute the covariance.

b. Compute the correlation coefficient. (57,19) (24,8) (18,6) (3,1) ( 3,1) (36,12) (60,20) (45,15) (45,15) (42,14) (6,2) a. The covariance is ( round to three decimals places as needed

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
