You only have to solve the problem. You do not have to do all the other parts specified in the problem (i.e. calculate error, plot or repeat the problem).

Please solve by hand, wirte neatly, answer all parts and do not skip steps.

17.3 Use least-squares regression to fit a straight line to 6 9 11 12 15 17 19 y l 5 6 10 12 Along with the slope and intercept, compute the standard error of the estimate and the correlation coefficient. Plot the data and the regression line. Then repeat the problem, but regress x versus y that is, switch the variables. Interpret your results
