Extracted text: 11.32 A chemist is interested in determining the weight loss y of a particular compound as a function of the amount of time the compound is exposed to the air. The data in the following table give the weight losses associated with n - 12 settings of the independent variable, exposure time. Weight Loss and Exposure Time Data Weight Loss,y (in pounds) 4.3 5.5 6.8 8.0 4.0 5.2 Exposure Time (in hours) 4 Weight Loss,y (in pounds) Exposure Time (in hours) 6.6 7.5 2.0 4.0 5.7 6.5 4 4 7 a. Determine the least-squares prediction equation for the model b. Test H0: β1S 0; give the p-value for Ha-A > 0, and draw conclusions
