A scientist is hoping to compare the levels of DDT toxin found in three species of fish in a local river. He randomly samples 7 of each species to use in the analysis. For each fish, he measures the amount of DDT toxin present. The data is shown below:
Ideally he will be able to determine if a difference exists in the population of DDT toxins found in the three fish species. The test statistic was determined to be H = 11.718. State the appropriate conclusion when testing at α = 0.025.
◦ There is insufficient evidence to indicate that the distributions of DDT toxins for the three species are identical.
◦ There is insufficient evidence to indicate that the distributions of DDT toxins for the three species differ in location.
◦ There is sufficient evidence to indicate that the distributions of DDT toxins for the three species differ in location.
◦ There is sufficient evidence to indicate that the distributions of DDT toxins for the three species are identical.
