cal Engineers A and B studied the effect of temperature and stirring rate on the yield of a certain product. Both engineers ran the process 16 times and calculated the correlation coefficients among the three parameters (temperature, stirring rate, and product yield): Correlation coefficient between Engineer A Engineer B Temperature and Stirring rate Temperature and Stirring rate and Product yield Product yield 0.9064 0.0000 0.7323 0.7513 0.0009 0.7707 (A) For the experiment of Engineer A, do these data provide good evidence that increasing the temperature will increase the product yield? Explain why or why not. (B) For the experiment of Engineer A, do these data provide good evidence that increasing the stirring rate will increase the product yield? Explain why or why not. (C) For the experiment of Engineer B, do these data provide good evidence that the product yield is unaffected by temperature? Explain why or why not. (D) For the experiment of Engineer B, do these data provide good evidence that increasing the stirring rate will increase the product yield? Explain why or why not. (E) Who (Engineer A or Engineer B) designed the experiment better? Why?
