Unformatted text preview: are the same. 3. Finding the signed ranks, we see that w + = 13 + 14 + 15 = 42 and w-= 1 + 2 + ... + 12 = 78. We see that w min = w + > w min0 . 05 = 25 and we cannot reject the hypothesis that the two means are the same. We see that this result contradicts the result of the sign test for the same signiﬁcance level. Since the signed rank test is generally better, we would be better oﬀ going with this result. 1...
