Characteristic Line and Security Market Line You are given the following set of data: HISTORICAL RATES OF RETURN NYSE -26.5% 37.2 23.8 Year Stock X -12.0% 24.0 11.0 6.0 11.4 19.9 16.6 2 4 6.6 20.5 30.6 a. Use a spreadsheet (or a calculator with a linear regression function) to determine Stock X's beta coefficient. Round your answer to two decimal places. Beta = b. Determine the arithmetic average rates of return for Stock X and the NYSE over the period given. Calculate the standard deviations of returns for both Stock X and the NYSE. Round your answers to two decimal places Stock X NYSE Average return, Avg T Standard deviation, C. Assume that the situation during Years 1 to 7 is expected to prevail in the future (i.e.,TX = rx ,Average ,rM = rM,Average , TAI,Average , and both ox and bx in the future will equal their past values). Also assume that Stock X is in equilibrium that is, it plots on the Security Market Line. What is the risk-free rate? Round your answer to two decimal places
