Let the price level of a certain country be 107.9 in 1994, 111.5 in 1995 and 114.5 in 1996.

(2) If the average of inflation in the previous two years is used as the expected value of inflation in the third year, calculate the expected inflation rate in 1997?

(3) If the nominal interest rate in 1997 is 6%, the real interest rate for that year is calculated.
