Question: let x be an unknown variable let y1 x...

Let x be an unknown variable. Let y1 = x + e1 and y2 = x + e2 be two measurements of x, where e1, e2 are two independent measurement noises represented by a Gaussian distribution N (0, 1) and N (0, 2), respectively. Determine the least-squares estimate of x. Express your solution in terms of y1 and y2 and show your derivation.
