You are given the following set of data: a. Use a spreadsheet (or a calculator with a linear regression function) to determine Stock X 's beta coefficient. Do not round intermeciate calculations. Rloind your answer to two decrnal places. b. Dotermine the arithmetic average rates of return for Stock X and the NYSE over the period given. Colculate the srandard deviations of returrs far beth 5 tock X and the krst. Do not round intermediate calculations. Round your answers to two decimal ploces. values). Also assume that Stock x is in equiliberium - that is, it plots on the Security Morket Line. What is the risk-free rate? Do not round intermediate calculationk. Rlound yout answer to two decimal places. d. Plot the Secunty Market Line. Choose the correct groph. The correct graph is Choose the correct grogh. The correct greght is e. Suppose you hold a large, well-diversified portfolio and are considering adding to that portfolio anther Stock X or another stock, Stock Y, which has the same beta as Stock X but a higher standard deviation of returns. Stacks X and Y have the same expected returns: rX=rY=10.6%. Which stock should you choose? In theory, you should as far as
