A chemical engineer is studying the effect of temperature and stining rate on the yield of a certain product. The process is run 16 times, at the settings indicated in the following table. The units for yield are percent of a theoretical maximum. Temperature (*C) Stirring Rate (1pm) Yield (%) 110 30 70.27 110 32 72.29 111 34 72.57 111 36 74.69 112 38 76.09 112 40 73.14 114 75.61 114 44 69.56 117 74.41 117 73.49 122 79.18 122 52 75.44 130 54 81.71 130 56 83.03 143 58 76.98 143 60 80.99 Compute the correlation between temperature and yield, between stinring rate and yield, and between temperature and stiring rate. Do these data provide good evidence that increasing the temperature causes the yield to increase, within the range of the data? Or might the result be due to confounding? Explain. Do these data provide good evidence that increasing the stiring rate causes the yield to increase, within the range of the data? Or might the result be due to confounding? Explain. a. Б. C.
