5.28 Measuring water quality. Biochemical oxygen demand (BOD) measures organic
pollutants in water by measuring the amount of oxygen consumed by microorganisms
that break down these compounds. BOD is hard to measure accurately. Total organic
carbon (TOC) is easy to measure, so it is common to measure TOC and use regres-
sion to predict BOD. A typical regression equation for water entering a municipal
treatment plant is ¹1
BOD = -55.43 +1.507 TOC
Both BOD and TOC are measured in milligrams per liter of water.
(a) What does the slope of this line say about the relationship between BOD and
TOC?
(b) What is the predicted BOD when TOC = 0? Values of BOD less than 0 are
impossible. Why do you think the prediction gives an impossible value?
Expert Solution
Step 1
Given:
Regression equation is:
BOD=-55.43+1.507(TOC)
where BOD=biochemical oxygen demand
TOC=total organic carbon
