The Predictor that is New Zealandmoney supply is statistically significant as shown from the p value of the concerned variable. Answer bThe p value of the intercept is 0.0000. This means the null hypothesis of nonsignificance of the model is rejected implying significance of the intercept term. Therefore,the intercept is required for the model.
