Refer to the U.S. Army Corps of Engineers data on contaminated fish, saved in the FISHDDT file. The results of an ANOVA and Tukey multiple-comparison analysis to compare the three fish species (channel catfish, largemouth bass, and smallmouth buffalo) on the dependent variable length (in centimeters) are shown in the following MINITAB printout.

a. Is there sufficient evidence (at α = .01) to conclude that the mean lengths differ among the three fish species?
b. What is the experiment wise error rate for the Tukey multiple comparisons?
c. Locate the confidence interval for the difference (mbass - mcatfish). Are the two means significantly different? If so, which mean is significantly larger?
d. Locate the confidence interval for the difference (mbuffalo - mcatfish). Are the two means significantly different? If so, which mean is significantly larger?
e. Locate the confidence interval for the difference (mbuffalo- mbass). Are the two means significantly different? If so, which mean is significantly larger?
