Assume that the Pure Expectation Theory determines interest rates in the markets. Today's market rates for different maturities are as follows: 1year=3%2years=4.8%3years=5.3%4years=6.3%5years=8% What is the implied 1 year interest rate for investing in 4 years? Enter your answer as a percentage, without the percentage sign ('\%'), and rounded to 1 decimal. For example, if your answer is 0.12345, this is equivalent to 12.345%, so just enter 12.4
