Let X and Y be random variables with respective means μx and μy, respective variances and o, and correlation coefficient p. Fit the line Y = a + bx by the method of least squares to the probability distribution by minimizing the expectation K(a, b) = E[(Y — a – bX)²] with respect to a and b. Your final answer must be two expressions, one for â and another one for 6. Please show all your work and simplify them as much as possible.
