To test for any significant difference in the mean number of hours between breakdowns for four machines, the following data were obtained. Excel File: data13-19.xlsx Difference Absolute Value T1 - T₂ T1-T3 14 The mean times between breakdowns are 7.1, 9.1, 9.9 and 11.4 hours respectively. In the analysis of variance, MSTR = 19.26 and MSE = .97. Use the Bonferroni adjustment to test for a significant difference between all pairs of means. Assume that a maximum overall experiment error rate of .05 is desired. T2 - T3 T2 - T4 There are six pairwise comparisons among the 4 machines. What error rate should be used for each pairwise comparison (to 4 decimals)? 0.0490X T3 - T4 Using t = 2.927 for the above error rate, calculate the Bonferroni LSD value (to 2 decimals). ♡ 1.62 Complete the table below to determine whether there are any significant differences between population means (to 1 decimal). -2.0 -2.8 -4.3 X -0.8 -2.3 X -1.5 X X X Conclusion Significant difference Significant difference Significant difference Machine 1 6.4 7.8 5.3 7.4 No significant difference ✓ 8.4 7.3 Significant difference Machine 2 8.7 7.4 9.4 10.1 9.2 9.8 No significant difference ✓ Machine 3 11.1 10.3 9.7 10.3 9.2 8.8 Machine 4 9.9 12.8 12.1 10.8 11.3 11.5
