Problem 1 Given m data points (31, m), {3:2, 332}, . . . , (33m, gm). We want to use the least squares method to t a line y = on + C13: to these data points. Unlike the concrete examples during class, the goal of this problem is to derive a general formula for the least squares solution [(50, (51). a,' Set 11p the least squares problem A3: = b (i.e. specify what is the matrix A and the vector b). bf Compute ATA and its inverse [ATA]_1. cf Derive the formula for the least squares solution (so, 81]
