Ten treatments were compared for their effect on the liver in mice.There were 13 animals in each treatment group. The ANOVA gave MS(within) = 0.5842. The mean liver weights are given in the table.37

(a) Use Fisher LSD intervals to compare all pairs of means with aCW. = 0.05 and summarize the results in a table similar to Table 11.9.4. [First note that the sample sizes are equal; hence the same margin of error (t × SEDn) can be used for all comparisons. Furthermore, since a summary table is desired, the actual intervals need not be computed: Simply check if |dab| > t × SEDab. If it is, then the computed interval would not contain zero, so the difference is significant. Finally, not all possible comparisons (there are 45) need to be checked: when using the method of underlining to summarize results, once a subarray of groups has been underlined all comparisons within the subarray are considered nonsignificant.]
(b) If Bonferroni's method is used with aew = 0.05 instead of Fisher's LSD in part (a), are any pairs of means significantly different?
