Samples of cream from each of 10 dairies (A to J) are each divided into two portions. One portion from each is sent to Labratory I and the other to Labratory II, for bacterium counts. The counts (thousands bacteria/ml) are Lab I Lab II 15.9 16.5 12.2 11.8 13.3 14.1 12.7 14.1 15.4 16.6 15.4 15.3 14.3 14.9 15.9 16.4 13.5 14.7 13.1 13.2 Use the Wilcoxon signed-rank test to assess the evidence for any consistent difference between labratories for subsamples from the same dairy. Calculate differences as Lab II - Lab I. What is the sum of the negative ranks (W*)? What is the sum of the positive ranks (W+)? What type of test is this?
