[Regression Analysis] How do you solve this? 7. a) In fitting the model Y = ßo + B1X1 + ß₂X₂ + € to a data set of n = 7 entities, weobtained the following [XTX]-¹ matrix:1164645488 0 -7840 588 0-784 0 196If S = 1.1495 and Y = 1.714 - 1.107X₁ -0.036X2, perform the following:a) Test 3₂ = 0 vs 3₂ <0 at the 5% significance level.b) Construct a 95% confidence interval for ₁. Based on this interval, decide whetherX₁ should be retained in the model.
