Jane is doing a test on the effect of foreign direct investment and unemployment on the US GDP Growth performance, There are 33 observations. Growth = 13.00 + 0.456 FDI + 0.277 Unemployment se: (5.98) (0.132) (0.116) Durbin-Watson Stat: 1.768 R2: 0.427 Note: The estimated regression is linear model with Growth is GDP growth, FDI is inflow of foreign direct investment in percentage of GDP, Unemployment is unemployment rate. a) Test (at 5%) the significance of all regressors from the...
