4.Suppose you estimate a sample OLS regression model using 20 observations (for i = 1,2, ..., 20). The resulted regression equationis: Yi = 2.11 + 3.58Xi +εi. Yi, Xi, and εi denote the dependent variable, independent variable, and the regression residual,respectively. If Xi is equal to 2 for i = 1,2 .... 4； equal to 3 fori = 5,6 ,..., 10； equal to 11 for i = 11, 12； equal to 14 for i =13, 14, ... 20, what is the value of Y?
(A)30.75
(B) 28.96
(C) 26.12
(D) It cannot be determined.
(E) None of the above choices (a)-(d).
