I C) Give the 95% confidence interval for [3’2 and explain whether it is statistically significant or not. I D) Also give the t-stat and test the significance of X3 ,i.e., test H0: )63 = 0 I E) Find T88, E88, and R88. - F) Find 132:1de2 I G) Test the overall significance if the regression, i.e. H0: 52 =53 = 0 I H) Test whether the coefficients of X2 and X3 are equal in magnitude but opposite in signs That is H0: 52 +133 = 0 note: Assume normal distribution holds (use normal table instead of students-t table for critical values) ...
