Dr. Tiny is interested in the weights of African elephants (Loxodonta africana) and Asian elephants (Elephas maximus). 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?
