The operation of a plating bath is studied. A particular plating operation requires a preparation time and the plating time for the job. The preparation time and plating time both fluctuate depending upon the job. The readings for ten jobs are given in the table. Make a scatter diagram and estimate the correlation coefficient. Can you conclude that the two are correlated? Explain your answer.
