The following are endotoxin levels in units per milligram of dust sampled from children's mattresses, organized by children's proximity to farms Apply the Kruskal Wallis test at a 5% level of significance.

Miles Miles Miles A. There is significant evidence at alpha-0.05 t o show that the populations of endotoxin levels in children living varying distances from operating farms are not equal B. There is not significant evidence at alpha-0.05 to show that the populations of endotoxin levels in children living varying distances from operating farms are not equal C. There are not enough data points to reach a conclusion. D. The tied value makes the analvsis suspect.
