For each of the following sets of statements, state whether the conclusion is correct or incorrect based on the facts given, and explain the rationales of your answer in no more than four sentences. (No marks will be given for only indicating the conclusion as correct or incorrect without any explanation.) a. Facts (given): When an interval variable Y is regressed on three interval variables X1, X2, and X3, simultaneously (i.e., within the same multiple regression equation), the multiple correlation coefficient and the regression coefficients of X1 and X2 are all statistically significant and the regression coefficient of X3 is not statistically significant. Conclusion: When Y is regressed on X3 (in a bivariate regression analysis). the regression coefficient of X3 is not necessarily non-significant (statistically).
