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 $\mathrm { H } = 11.718$. State the appropriate conclusion when testing at $\alpha = 0.025$.

A) There is insufficient evidence to indicate that the distributions of DDT toxins for the three species are identical.
B) There is sufficient evidence to indicate that the distributions of DDT toxins for the three species are identical.
C) There is sufficient evidence to indicate that the distributions of DDT toxins for the three species differ in location.
D) There is insufficient evidence to indicate that the distributions of DDT toxins for the three species differ in location.
