She doesn’t have any reason to believe that one is larger than the other, but wants to test whether that is the case. She has measured the following weights (lbs.) from 4 African elephants: 12,000 17,000 11,000 13,000 She has measured the following weights (lbs.) from 8 Asian elephants. 12,000 9,000 13,000 10,000 14,000 8,000 7,000 11,000 Dr. Tiny plans to run a Wilcoxon-Mann-Whitney test about these elephant species’ weights. She is planning to use the following random variable definitions. let X = the weight (in lbs.) of a randomly selected African elephant let Y = the weight (in lbs.) of a randomly selected Asian elephant What is the value of the test statistic?
