In a regression, the t-statistic measures: Select one: a. The amount of variance the regression model can explain b. Economic Plausibility c. The linearity of a straight-line regression d. The predictive power of a X variable A p value measures: Select one: a. the probability that our model is valid and useful b. the "goodness of fit" between the actual and predicted observations c. the amount of variance the regression model cannot explain d. the probability that the coefficient is not valid
