b. It the true model, satisfying Gauss-Markov assumptions, in the population is:  final =β0​+β1​ attend +β2​ stud y+u Whore final indicates the final grade obtained in exam, attend is attendance rate and study is the number of hours studied in a week, then the OLS estimator ( β^​1​ ) from the above regression is unbiased. A researcher could not collect datn nbous study and estimated the following simple linear regression model: fmal​=βˉ​0​+β~​1​ attend  i. Analytically derive an expression for E[β~​1​] [10 marks] ii. Comment about the unbiasedness of βˉ​1​ and justify your answer. [ 3 marks]
