A Scientist Is Hoping to Compare the Levels of DDT $\quad$

question 31

Multiple Choice

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: $\quad$ $\quad$$\text { Species }$
$\begin{array}{c|c|c}1 & 2 & 3 \\\hline 8.4 & 4.5 & 0.58 \\15 & 4.2 & 2 \\25 & 3 & 2.2 \\5.6 & 2.3 & 7.4 \\4.6 & 2.5 & 0.35 \\8.2 & 6.8 & 1.9 \\6.1 & 5.1 & 2.7\end{array}$
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 ? = 0.025.

• A) There is sufficient evidence to indicate that the distributions of DDT toxins for the three species are identical.
• B) There is insufficient 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.
