The values in bracket are standard errors
a) Comment on the signs of each the variables in the model.
b) Interpret and explain individual coefficients.
c) Suppose X3 increases by 2 units; what is the expected impact of this change on Y?
d) Comment on the explanatory power of the regression (goodness of fit with )
e) Test whether the coefficient of X2 is significant or not using the Standard error test, at 5%
