(b) What is the estimate of expected NOx emission rate when burner area liberation rate equals 245? (Round your answer to two decimal places.)
ppm
(c) Estimate the amount by which you expect NO emission rate to change when burner area liberation rate is decreased by 50. (Round your answer to two decimal places.)
ppm
(d) Would you use the estimated regression line to predict emission rate for a liberation rate of 500? Why or why not?
Yes, the data is perfectly linear, thus lending to accurate predictions.
Yes, this value is…
