(-3.5)/1.6396 = -2.1347 Critical Value: Zα/2= Z0.05/2= @qnorm(1-0.05/2)= 1.96 When comparing the test statistic to the critical value: Z=2.1347>1.96‚ we reject the null hypothesis. We can calculate the P-value using the EViews command: Show @tdist (t‚ d.f) In this EViews command‚ t stands for the appropriate test statistic and d.f are the degrees of freedom. The appropriate test statistic was calculated above‚ namely Z=2.1347. For the degrees of freedom‚ we can insert NA+NB-2. Show @tdist (2
