Rayon whiteness is an important factor for scientists dealing in fabric quality. Whiteness is affected by pulp quality and other processing variables. Some of the variables include acid bath temperature, ◦C (x1); cascade acid concentration, % (x2); water temperature, ◦C (x3); sulfide concentration, % (x4); amount of chlorine bleach, lb/min (x5); and blanket finish temperature, ◦C (x6). A set of data (click on it for data) from rayon specimens is given. The response, y, is the measure of whiteness.
Do a correlation analysis. Do your regression analysis and provide an acceptable predictive model. Assess your model adequacy. Provide a summary of your work (table version of all your results) with interpretation of your results.
