Question 4 An experiment was conducted to measure the pollution level in the ground- water at four different locations. The pollution levels were measured at each of the locations at five different time points as given in the table below. Time Location 1 Location 2 Location 3 Location 4 1 19.2 22.3 17.6 31.9 29.6 33.2 17.2 16.4 17.0 25.5 25.7 24.3 22.1 23.7 20.3 2 3 4 5 18.4 30.2 18.9 26.1 24.3 Is there any evidence to support the claim that the pollution levels are different at the four locations? Make a graphical presentation that illustrates the differences between the pollution levels at the four locations.
