A Scientist Is Hoping to Compare the Levels of DDT $\alpha = 0.05$

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. Identify the rejection region that should be used to conduct the Kruskal-Wallis H-Test at $\alpha = 0.05$ .

A) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { H } > 5.99147$
B) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { H } > 9.48773$
C) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { H } > 7.37776$
D) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { H } > 7.81473$
