Long question

Suppose we have the following returns for large-company stocks and Treasury bills over a six year period:

Year	Large Company	US Treasury Bill
1	3.69	4.75
2	14.48	3.59
3	19.27	4.18
4	-14.41	5.91
5	-31.90	5.32
6	37.51	6.41

a.	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.)

	Average returns
Large company stocks	%
T-bills	%

b.	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	%

c-1

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.)
