I am not sure how my answers are incorrect

A stock's returns have the following distribution: Demand for the Probability of This Rate of Return If Company's Products Demand Occurring This Demand Occurs Weak 0.1 (44%) Below average (15) Average 15 Above average 21 Strong 0.2 Assume the risk-free rate is 2%. Calculate the stock's expected return, standard deviation, coefficient of variation, and Sharpe ratio. Do not round intermediate calculations. Round your answers to two decimal places. Stock's expected return: 9.7 % Standard deviation: 5.01 % Coefficient of variation: 51.70 Sharpe ratio: 1.54
