QUESTION 8Assume that we estimated the following model by OLS:y =B₁ + B₂x + u.The sample size of the data is n-62. We calculated that the standard errors for B. and ß. are se(B)=1 and se(B)-2. Also, the estimates for B.and B. are B-3 and 3.-5. We want to test:Ho: Bi=4Hi: Bi>4.for a 0.05 significance level. What is the t statistic? [We denote the estimates by bold font]0³.2O b..2091Od..1
