To test for any significant difference in the number of hours between breakdowns for four machines, the following data were obtained. Machine 1 Machine 2 Machine 3 Machine 4 6.6 9.1 10.9 9.6 8.1 7.8 9.9 12.4 5.6 9.7 9.4 11.7 7.8 10.3 10.1 10.6 8.8 9.5 8.8 10.9 7.5 10.0 8.5 11.4 Use Fisher's LSD procedure to test for the equality of the means for machines 2 and 4. Use a 0.05 level of significance.   Find the value of LSD. (Round your answer to two decimal places.) LSD =   Find the pairwise absolute difference between sample means for machines 2 and 4.  x2 − x4= What conclusion can you draw after carrying out this test? There is a significant difference between the means for machines 2 and 4. There is not a significant difference between the means for machines 2 and 4.
