Chapter 12: Simple Linear Regression and Correlationb. Scatter plot of the data:BOD mass loading (x) vs BOD mass removal (y)90807060y:504030201000 50 100 150x:There is a strong linear relationship between BOD mass loading and BOD mass removal.As the loading increases, so does the removal. The two outliers seen on each of theboxplots are seen to be correlated here. There is one observation that appears not tomatch the liner pattern. This value is (37, 9). One might have expected a larger value forBOD mass removal.5.a. The scatter plot with axes intersecting at (0,0) is shown below.Temperature (x) vs Elongation (y)250200150y:1005000 20 40 60 80 100x:354
