Essay

In testing the hypotheses: $H _ { 0 } :$ The two population locations are the same $H _ { 1 } :$ The location of population A is to the right of the location of population B,
with data drawn from a matched pairs experiment, the following statistics are calculated: $n = 27$ , $T ^ { + } = 271$ , $T ^ { - } = 107$ .
