E. Coli Colonies in Riverwater Four samples of water were taken at six different locations along a river and measurements were obtained of the amount of E. Coli colonies within the water asgiven in DS 11.1.9. Investigate whether there is any evidence that the E. Coli pollution levels are different at the six locations. Location 6 is the highest point upstream, and location 1 is the furthest point downstream. There is a polluting source between locations 5 and 6. Make a graphical presentation that illustrates the differences between the E. Coli levels at the six locations. Which location has the highest E. Coli level? Which location has the smallest E.
