Suppose You Are to Test for Equality of Four Different $H _ { 0 } : \mu _ { d } = \mu _ { B } = \mu _ { C } = \mu _ { D }$

Essay

Suppose you are to test for equality of four different population means, with $H _ { 0 } : \mu _ { d } = \mu _ { B } = \mu _ { C } = \mu _ { D }$ . Write the hypotheses for the paired tests. Use methods of probability to explain why the process of ANOVA has a higher degree of confidence than testing each of the pairs separately.
