(b) Using R-Studio, estimate a regression equation to determine the effect of the real interest
rates, the exchange rate and the GDP growth rate on the Merchandise trade (% of GDP). (All
codes and regression output should be provided). NOTE: R-Studio should only be used for
obtaining the regression output and the regression equation.
(1) Write down the regression equation.
(11) Interpret the coefficients and determine which of the individual coefficients in the
regression model are statistically significant. In responding, construct and test any
appropriate hypothesis.
(iii) Interpret the coefficient of determination.
(iv)Using the 5% level of significance, determine and discuss whether the overall regression
equation is statistically significant. In responding, construct and test any appropriate
hypothesis.
(v) Determine and interpret the confidence interval for the independent variable(s).
