Question 5 For a simple linear regression model Y₁ = a + Bxi + Ei, we have collected 15 samples. Suppose that we have = 0.85, Y 46.74. When proofreading, we found that one data point is recorded incorrectly. The correct data is (1.2, 32.6), which is = 25.60, Sax = 19.56, Say = 32.54, SYY = recorded as (1.5, 32.3). 1 Find the correct OLS estimators for a and 3. Test Ho 30 versus H₁B #0 at a = 0.01. : 2
