Question An estimation of the amount of GDP (Y, R billions) as a function of government expenditure
(X2, R billions) and exports (X3, R billions) over the period 1980 - 2012 (n=33) was done,
and the following results were obtained:
-1336.049 + 12.7413X2 + 85.7640X3
(175 2725) 0.9123) (8.8019)
R2 = 08906; ESS = 42782953; RSS = 525462.2
2. Interpret the estimated parameters b2 and 63, indicating and explaining whether or not
their signs make economic sense.
b. Set up two-tailed hypothesis tests for each of b2 and b3, and test their significance at the 1% level​
