Suppose we have the following Treasury bill returns and inflation rates over an eight year period:

Year	Treasury Bills	Inflation
1	7.55%	9.02%
2	8.29	12.69
3	6.15	7.24
4	5.43	5.20
5	5.83	7.10
6	8.04	9.44
7	11.00	13.72
8	12.58	13.05

b.	Calculate the standard deviation of Treasury bill returns and inflation over this period. (Do not round intermediate calculations and round your final answers to 2 decimal places. (e.g., 32.16))
