Calculating Arithmetic and geomateric averages, Average returns, standard deviation, average risk premium.

Suppose we have the following returns for large-company stocks and Treasury bills over a six year period: Calculate the arithmetic average returns for large-company stocks and T-bills over this period. (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) Calculate the standard deviation of the returns for large-company stocks and T-bills over this period. (Do not round Intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) Standard deviation Large company stocks % T-bills % Calculate the observed risk premium in each year for the large-company stocks versus the T-bills. What was the average risk premium over this period? (Negative amount should be Indicated by a minus sign. Do not round Intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) Average risk premium % Calculate the observed risk premium in each year for the large-company stocks versus the T-bills. What was the standard deviation of the risk premium over this period? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
