Use the Following Sample Data to Answer the Next

question 32

Short Answer

Use the following sample data to answer the next questions. Certain creeks
tend to accumulate sandbars that block water flow and negatively affect fish
habitat. Biologists researching the formation and erosion of these sandbars
attempted to discourage sandbar buildup by installing wood structures that would
increase erosion in the creekbed. Researchers added differing numbers of wood
structures to two similar, adjacent study creeks. Fish response was then measured
by randomly sampling the number of fish at 11 equally-sized portions of the
creeks. Use the Wilcoxon Rank-Sum Test with a .05 significance level to test the
claim that, after adding the wood structures, both creeks have samples that come from populations with the same median number of native fish.
