Engineers periodically analyze water samples for various types of organic material. The total organic carbon (TOC) level

Question:

Engineers periodically analyze water samples for various types of organic material. The total organic carbon (TOC) level was measured in water samples collected at two sewage treatment sites in England. The accompanying table gives the summary information on the TOC levels (measured in mg/L) found in the rivers adjacent to the two sewage facilities. Since the river at the Foxcote sewage treatment works was subject to periodic spillovers, not far upstream of the plant’s intake, it is believed that the TOC levels found at Foxcote will have greater variation than the levels at Bedford. Does the sample information support this hypothesis? Test at α = .05.
