Question 1

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:

Species


Ideally he will be able to determine if a difference exists in the population of DDT toxins found in the three fish species. Identify the test statistic for the Kruskal-Wallis H-Test.
◦ H = 17.0
◦ H = 5.714
◦ H = 11.718
◦ H = 10.286

Question 2

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:

Species


Ideally he will be able to determine if a difference exists in the population of DDT toxins found in the three fish species. Identify the rejection region that should be used to conduct the Kruskal-Wallis H-Test at α = 0.05.
◦ Reject H0 if H > 9.48773
◦ Reject H0 if H > 7.37776
◦ Reject H0 if H > 5.99147
◦ Reject H0 if H > 7.81473
