a. Compute the annual returns for 2017 through 2021 (e.g., each year's return) of an equally weighted portfolio of Norvell stock and Napier stock.

b. You must now compute the standard deviation of the annual returns on the portfolio described in part a using two methods. For part b, use the actual annual returns of the equally weighted portfolio calculated in part a to calculate the portfolio standard deviation.

c. For part c, use the equation for the variance of a 2-asset portfolio that includes the security weights, the variances of each of the securities, and the covariance between the returns of the two securities. How do your answers compare?

Norvell=17.72% Estimated Napier=21.15% Norvell=17.72% Estimated Napier=21.15%
