Question: Suppose (X, Y) satisfy the least squares assumptions, and, in addition, u, is N(0, of) and is independent of X A sample of size

Suppose (X, Y) satisfy the least squares assumptions, and, in addition, u,

Suppose (X, Y) satisfy the least squares assumptions, and, in addition, u, is N(0, of) and is independent of X A sample of size n 30 yields: Y = 43.2 + 61.5X, R2 = 0.54, SER = 1.52 (10.2) (7.4) where the numbers in parentheses are the homoscedastic-only standard errors for the regression coefficients. a. Construct a 95% confidence interval for Bo. b. Test H,: B, = 55 vs H, # 55 at the 5% level. c. Test Ho: B, = 55 vs H, > 55 at the 5% level. %3D
