Question

Cicadas are flying, plant-eating insects. One particular species, the 13-year cicada (Magicicada), spends five juvenile stages in underground burrows. During the 13 years underground, the cicadas grow from approximately the size of a small ant to nearly the size of an adult cicada. Every 13 years, this species then emerges from their burrows as adults. The adult body weights (BW) in grams and body lengths (BL) in millimeters are given for three different species of these 13-year cicadas in the following table.
a. Is there any significant difference in the body weights of adult cicadas with respect to species? Construct a one-way ANOVA table and test for the difference at the 0.01 level of significance.
b. Is there any significant difference in the body lengths of adult cicadas with respect to species? Construct a one-way ANOVA table and test for the difference at the 0.01 level of significance.
