Estimation of equation (2) provides us with the estimated relation that allows us to test whether 0 = 0 and 1 = 1. Should these hold, we could say that there is no evidence against PPP. To test these statements, we use first a t test to test them individually and then F test to see if they hold jointly. The t test result can be seen immediately from the confidence intervals, (1.39; 1.58) for the intercept term, and (0.54; 0.58) for the slope. Neither of these contain the hypothesized values, and therefore we will reject the individually stated claims. The F test statistic for the joint test provides a value of 21512 with zero p-value. The joint claim is clearly rejected. Our conclusion is that the data provides evidence against PPP
