The price-earnings (PE) ratios of a sample of stocks have a mean value of 13.5 and a standard deviation of 2. If the PE ratios have a bell shaped distribution, use the 68-95-99.7 Rule to estimate the percentage of PE ratios that fall between: A. 7.5 and 19.5. Percentage = % B. 11.5 and 15.5. Percentage = % C. 9.5 and 17.5. Percentage = %

Suppose your expectations regarding the stock price are as follows: State of the Market Probability Ending Price HPR (including dividends) Boom 0.28 $ 140 49.0% Normal growth 0.22 110 17.0 Recession 0.50 80 -13.5 Use the equations E(r) = Σ p(s) r(s) and σ^2 = Σ p(s) [r(s) - E(r)]^2 to compute the mean and standard deviation of the HPR on stocks. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Mean Standard deviation
