3. The spreadsheet (regressio.xls) contains data on excess returns (return net of risk-free rate) of a stock (BOISE) and a market portfolio. If an investor is interested in investing in a stock that has systematic risk exposure less than the market, would the investor be interested in investing in this stock? How much of the variation in the returns of the stock is explained by the variation of the market? Do the necessary computation and make your conclusion. Please present the related regression result in a table. 17 Marks]
