Use the Following Sample Data to Answer the Next

question 34

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 surface
insect 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. The response of surface insects to
the addition of wood structures was then measured by randomly sampling the
weights (in grams) of surface insects at 11 equally-sized locations in 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 of weights of surface insects. Use the following sample data to answer the next  questions.
