A sample of five observations is taken for two variables volume (V) and weight (W) and the values are recorded as follows: W 6 27 12 21 17 15 The mean values, standard deviations, and the covariances are computed for the sample and the obtained results are: The mean value for V is 16 and the mean value for W is 10. The standard deviation for V is 8.2462 and the standard deviation for W is 4.6368. The covariance between V and W is 26.5. Compute the sample covariance
