This problem has been solved!See the answer(a) Suppose you are given the following (x, y) data pairs. x 1 2 6y 2 3 9Find the least-squares equation for these data (rounded to three digits after the decimal).y= +x(b) Now suppose you are given these (x, y) data pairs. x 2 3 9y 1 2 6Find the least-squares equation for these data (rounded to three digits after the decimal).y = + x (c) In the data for parts (a) and (b), did we simply exchange the x and y values of each data pair? Yes No(d) Solve your answer from part (a) for x (rounded to three digits after the decimal).x = + yDo you get the least-squares equation of part (b) with the symbols x and y exchanged?YesNo (e) In general, suppose we have the least-squares equation y = a + bx for a set of data pairs (x, y). If we solve this equation for x, will we necessarily get the least-squares equation for the set of data pairs (y, x), (with x and y exchanged)? Explain using parts (a) through (d).In general, switching x and y values produces the same least-squares equation. Switching x and y values sometimes produces the same least-squares equation and sometimes it is different. In general, switching x and y values produces a different least-squares equation.
