h. The expected rates of return and the beta coefficients of the alternatives as supplied by a computer program the bank uses are as follows: (1) What is a beta coefficient, and how are betas used in risk analysis? (2) Do the expected returns appear to be related to each alternative's market risk? (3) Is it possible to choose among the alternatives on the basis of the information developed thus far? (4) Use the data given at the beginning of the problem to construct a graph that shows how the T-bill's, High Tech's, and Collections' beta coefficients are calculated. Discuss what the beta coefficient measures and explain how it is used in risk analysis
