Which of the following statements is false? (a) It has to be the case that R0287 and R.0258. (b) That motheduc and atheduc are jointly insignificant in the birth weight equation at the 1% significance level. (c) That motheduc and atheauc are jointly insignificant in the birth weight equation at the 5% significance level d) We use an Fstatistic to test this. (e) None of the above. 14. Calculate the F statistic that you would need to test for the overall significance of the regression (a) 4.69 (b) 4.11 (c) 5.32 (d) There is not enough information to calculate this.
