Explanation / Answer
A) Calculate the average return for Treasury bills and the average annual inflation rate (consumer price index) for this period. (Round your answers to 2 decimal places. (e.g., 32.16))
Average Return for Treasury bills = (10.15+11.05+8.76+8.05+8.58+10.92+13.79+15.63)/8
Average Return for Treasury bills = 10.87%
Average Return for Inflation = (12.25+15.67+9.98+7.69+9.98+12.45+16.65+16.55)/8
Average Return for Inflation = 12.65%
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))
Answer
Standard deviation for Treasury bills is 2.66%
Standard deviation for Inflation is 3.37%
Working
Standard deviation for Treasury bills = (49.39/(8-1))^(1/2)
Standard deviation for Treasury bills = 2.66%
Standard deviation for Inflation = (79.39/(8-1))^(1/2)
Standard deviation for Inflation =3.37%
C) What was the average real return for Treasury bills over this period?(Negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))
The average real return for Treasury bills = (1+Average Return for Treasury bills )/(1+Average Return for Inflation) - 1
The average real return for Treasury bills = (1+10.87%)/(1+12.65%) - 1
The average real return for Treasury bills = - 1.58%
