Questions 1.11 to 1.12 require you to estimate the regression equation = + + (equation 2) where EXRATE and INF are the same as in Table 1 and IRATE is the real deposit rate of interest.
In this equation, inflation and interest rates are determinants of exchange rates.
Use Excel's Add-in to estimate equation 2

B) 2 changed from 0.25 (equation 1) to 0.54 (equation 2, both rounded to 2 decimals).
C) The change in 2 caused by the inclusion of IRATE in regression equation 2 indicates that there is merit in including IRATE.
