1. Analyze the data as a two way factorial design. 7. Johnson and Leone (Statistics and Experimental Design in Engineering and the Physical Sciences, Wiley, 1977) describe an experiment to investigate warping of copper plates. The two factors studied were the temperature and the copper content of the plates. The response variable was a measure of the amount of warping. The data were as follows: Temperature (°C) 50 75 100 125 40 17, 20 12,9 16, 12 21, 17 Copper Content (%) 60 80 24, 22 17, 12 25, 23 23, 22 16, 21 18, 13 18, 21 23, 2! 100 28, 27 27, 31 30, 23 29, 31
