Answer:
7.98; 0.92
Explanation:
First we calculate the rate of return on large company stock as follows:
Average nominal return = (0.15 + 0.07 + 0.04 + 0.18)/4 = 0.11
Average real rate: r = (1.11/1.028) - 1 = 7.98 percent
Now we solve the percent for U.S. Treasury Bills
Average nominal return = (0.06 + 0.03 + 0.02 + 0.04)/4 = 0.0375
Average real rate: r = (1.0375/1.028) - 1 = 0.92 percent
Hence, the answer is 7.98% for large-company stocks and 0.92% for Treasury Bills.
