Jason Jackson is attempting to evaluate two possible portfolios consisting of the same five assets but held in different proportions. He is particularly interested in using beta to compare the risk of the portfolios$$ and, in this$$ regard, has gathered the following$$ data: LOADING....

a$.$ Calculate the betas for portfolios A and B$.$

b$.$ Compare the risk of each portfolio to the market as well as to each other. Which portfolio is more$$ risky?
