It is believed thаt the % yield оf а certаin chemical prоcess can be mоdeled as a multiple linear regression model with regressors being (1) the # revolutions per minute of the mixer, and (2) the number of hours the mixer has run. Data and initial Excel output are shown below. Use alpha = 0.05. Accept these values in the Excel output as correct, even if you disagree. % Yield # Revs/min # Hours 14.8% 6.1 15,100 15.7% 7.2 14,500 18.1% 8.1 17,415 5.9% 2.1 5,600 6.6% 3 6,200 9.8% 3.1 9,900 7.6% 3.3 7,240 10.7% 5.4 10,100 ANOVA df SS MS F Significance F Regression 2 144.79 72.39 841.9 4.7E-07 Residual 5 0.4299 0.085 Total 7 145.22 Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept 0.312 0.291 1.072 0.033 -0.436 1.061 # Revs 0.541 0.150 3.609 0.015 0.156 0.927 # Hours 0.001 0.000 10.231 0.000 0.001 0.001 This copywritten question is part of a quiz or exam at Arizona State University. It may not be reproduced or posted without the permission of Dr. Linda Chattin. The model-predicted yield for 6.1 revs/min and 15,100 hours is [a]. The residual for the last data point (10.7% yield) in this problem is [b]. Select the best answers and/or the answers closest to yours.
