For the following data plot on regular, semi-log and log-log graph paper until you get a straight line. Determine the equation of this line using both methods; selected points and least squares. Plot these equations on the graph paper. Calculate the correlation coefficient. Assume P depends on Q. (P = f(Q)) P - 8.00, 5.60, 2.70, 1.20, 0.80, 0.40, 0.22

Q - 5, 10 , 18, 24, 31, 35, 43

Answer should be as follow :-

Selected points - P =14.88(0.9055)^Q

Least square - P=14.015(0.9073)^Q

r = -0.996
