ANOTHER STATITISTICS TASK!!Please provide quality answers for i will not accept wrong answers!

Problem 11. (15) Bivariate data (4, 10),(1, 3),(0, 2) is assumed to arise from the model

yi = b|xi 3| + ei, where b is a constant and ei are independent random variables.

(a) What assumptions are needed on ei so that it makes sense to perform least squares fit of a curve y = b|x 3| to the data?

(b) Given the above data, determine the least squares estimate for b.

For this problem we want you to calculate all the way to a fraction b = r where r and s are integers
