• A and B stocks.

This data is shown in the following table.

1. Calculate the means and standard deviations of the realized returns
2. Calculate the correlation coefficients between each pair of variables (A,M), (B, M), (A,B).
3. Calculate the covariances between each of the pairs of variables (A,M), (B, M), (A, B).
4. Determine the beta coefficients of each of the stocks
