To test for any significant difference in the mean number of hours between breakdowns for four machines, the following data were obtained. Machine 1 Machine 2 Machine 3 Machine 4 6.4 8.7 11.1 9.9 7.8 7.4 10.3 12.8 5.3 9.4 9.7 12.1 7.4 10.1 10.3 10.8 8.4 9.2 9.2 11.3 7.3 9.8 8.8 11.5 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. There are six pairwise comparisons among the 4 machines. What error rate should be used for each pairwise comparison (to 4 decimals)? Using t = 2.845 for the above error rate, calculate the Bonferroni LSD value (to 2 decimals).

Question
To test for any significant difference in the mean number of hours between breakdowns for four machines, the following data were obtained.
| Machine 1 | Machine 2 | Machine 3 | Machine 4 | |||
| 6.4 | 8.7 | 11.1 | 9.9 | |||
| 7.8 | 7.4 | 10.3 | 12.8 | |||
| 5.3 | 9.4 | 9.7 | 12.1 | |||
| 7.4 | 10.1 | 10.3 | 10.8 | |||

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.
There are six pairwise comparisons among the 4 machines. What error rate should be used for each pairwise comparison (to 4 decimals)?
Using t = 2.845 for the above error rate, calculate the Bonferroni LSD value (to 2 decimals).
