Question 69

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:  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

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\alpha = 0.05 .


A) Reject H0\mathrm { H } _ { 0 } if H>5.99147\mathrm { H } > 5.99147
B) Reject H0\mathrm { H } _ { 0 } if H>9.48773\mathrm { H } > 9.48773
C) Reject H0\mathrm { H } _ { 0 } if H>7.37776\mathrm { H } > 7.37776
D) Reject H0\mathrm { H } _ { 0 } if H>7.81473\mathrm { H } > 7.81473
