Five observations taken for two variables follow.

Xi- 4 6 11 4 14

Yi- 50 50 40 50 30

Compute the sample covariance (to 1 decimal and enter negative value as negative figure).

Interpret the sample covariance.

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.
