Consider the regression model y_i= β₁ + β₂x_2i+ β₃x_3i+e_i is known that X_2i: is exogenous. It is suspected that :r may be endogenous. Data on another variable ; is available. It is known that z_t; is correlated with X_3i, and is uncorreleated with Using data from this file, test the null hypothesis that x_3i is exogenous using a 1% significance level.

To get full marks for this question, you will need to construct a t-statistic from an auxiliary regression that you estimate by OLS, and be able to use Gretl to automatically generate a x² statistic as part of an estimation routine.

(a) Enter the t-statistic that you calculated 'manually for the test in the box below (rounded to 3 decimal places).

(b) Enter the x² statistic that Gretl generates for this test in the box below (rounded to 3 decimal places).
