Hypotheses: (H_{0}: M_{x}=M_{y}) versus (H_{1}: M_{x} eq M_{y}) with (n_{1}=12, n_{2}=15), and (S=170) Use the Mann-Whitney test

Question:

Hypotheses: \(H_{0}: M_{x}=M_{y}\) versus \(H_{1}: M_{x} eq M_{y}\) with \(n_{1}=12, n_{2}=15\), and \(S=170\)

Use the Mann-Whitney test to test the given hypotheses at the \(\alpha=0.05\) level of significance. The independent samples were obtained randomly.
