Hi, I've attached the question and my worked solution. I am confident I have the correct least squares straight line of best fit to the data to 2 d.p., but I'm unsure what is being asked in the next part. Am I to sub the xi values into the least squares straight line of best fit to acquire yi estimates? And if so, I know there will be variation. How would you explain the accuracy of such variation?
