6. To investigate the tradeoff between time to work and time to sleep, the following equation is estimated: Sleep = 3600 + 0.128 • totwrk – 10.08 • educ + 2.10 • age (4.58) 700, R2 = 0.102 %3D (112.14) (0.016) (1.35) Standard errors are in the parentheses. (2) Dropping educ and age from the equation gives: Sleep = 3780- 0.104 • totwrk (52.04) (0.012) n = 700, R = 0.099 %3D Are educ and age jointly significant in the original equation at the 5% level? Justify your answer. (When dF is 696, it is big enough to treat as infinity.) Your answer: The F statistic is (Round to the first decimal place). The critical value you find on the F-table is (Round to the first decimal place). Thus, educ and age are jointly significant in the original equation at the 5% level educ and age are not jointly significant in the original equation at the 5% level
