13. if you are doing a regression Yi=b1 b2 X2i+b3X3i+ei on a sample of 9 observation and you get the results that the value of t calculated for b2-2447, then the the p-value for t-test, note the significant level =001, and f calculated -9, then R square (2 points) herpesmicro.com_Tour-only-US-deplini empleaninche:971700005 40 02/21,634 PM Final Economie summer 2021 Economics Summer 2021) 0.97 14. If Yi=B1-B2 X2 + B3X3 . 34 X4 +ei and we are suspecting that we have the problem of Hetroschedasticity and we want to use the Glejser test to detect the problem, the number of regression that we should do on all independent variable is equal to (2 points) 6 15. if you are doing a regression Yi-B1-B2 X Ui on sample include 6 observations you calculated the error for each observation and they were as follow 2,2.5, -2, -3, ?, and according to Guass-Markov Theorem of Best linear Unbiased estimator the expected sigma square must be ? (2 points) 60 245 0 -51 45 one of the above
