Chemical Comparisons Narrative
A chemist was interested in examining the effects of three chemicals on a chemical process yield. Let , i = 1, 2, 3, represent the effects of the three chemicals, respectively, and y be the process yield. The following output was generated using statistical software.
Regression Analysis S = 14.01 R-Sq = 95.1% R-Sq(adj) = 92.1
Analysis of Variance
-Refer to Chemical Comparisons Narrative. Which variable, if any, should be removed from the model if a 0.05 level of significance is desired?
