Can you please help me with the following question:

Question 4 [26] Suppose that the random variables Y1, Y2, Y3, ..., Y, satisfy Yi = Bxit Ei, i = 1, 2, ..., n, where x1, x2, ..., x, are known fixed constants, and 61, 62, ..., En are independent random variables each with a N(0, 2) distribution, & unknown. (a) What is the distribution of Y;? (3) (b) Find the likelihood function of B and q2. (3) (c) What are the joint sufficient statistics for B and a?? (6) (d) Find the maximum likelihood estimators of (MLEs) of B and a2. (14)
