Answer #1
Year B
1 14.00%
2 -10.00%
3 -6.00%
4 5.00%
5 14.00%
6 5.00%
Average= 3.67%
Where
Average or Mean = Sum of all observations/Count of all observations
Year B C A = B observation - B average A = C observation - C average A*B
1 14.00% 13.00% 10.33% -1.00% -0.10%
2 -10.00% -14.00% -13.67% -28.00% 3.83%
3 -6.00% -4.00% -9.67% -18.00% 1.74%
4 5.00% 28.00% 1.33% 14.00% 0.19%
5 14.00% 8.00% 10.33% -6.00% -0.62%
6 5.00% 7.00% 1.33% -7.00% -0.09%
Average= 3.67% 6.33% Covariance= Sum of all A*Bs = 4.94%
