Problem 19E
The following data is representative of that reported in the article “An Experimental Correlation of Oxides of Nitrogen Emissions from Power Boilers Based on Field Data” (J. of Engr. for Power, July 1973: 165–170), with x = burner-area liberation rate (MBtu/hr-ft2) and y = NOx emission rate (ppm):
a. Assuming that the simple linear regression model is valid, obtain the least squares estimate of the true regression line.
b. What is the estimate of expected NOx emission rate when burner area liberation rate equals 225?
c. Estimate the amount by which you expect NOx emission rate to change when burner area liberation rate is decreased by 50.
d. Would you use the estimated regression line to predict emission rate for a liberation rate of 500? Why or why not?
