The data from Exercise 16.65 on weight (in grams) and length (in centimeters) from the nose to the beginning of the tail for four species of fish caught in Lake Laengelmaevesi, Finland. Consider both the weight and length data for possible analysis.
In Exercises 16.158-16.166, use the technology of your choice to do the following tasks.
a. Decide whether conducting a Kruskal-Wallis test on the data is reasonable. If so, also do parts (b)-(d).
b. Use a Kruskal-Wallis test to decide, at the 5% significance level, whether the data provide sufficient evidence to conclude that a difference exists among the means of the populations from which the samples were taken.
c. Interpret your results from part (b).
d. If a one-way ANOVA test was performed on the data in Section 16.3, compare your results there to those obtained here.
