The following graphs are for data on the species richness in randomly selected rain forest plots, defined as the number of tree species in a plot divided by the number of trees in the plot. ANOVA may not be trustworthy for this data.
PLEASE HELP! The answer is NOT B and D, or B and C. I only have one try left!!!!
Homework Answers
Following is the rule of thumb: if the largest sample standard deviation divided by the smallest sample standard deviation is not greater than two, then assume that the population variances are equal.
Here
\(\frac{0.1472}{0.1134}=1.3\)
So rule of thumb is not violated.
From the output and box plots, it can be observed that the sample size is less than 30 , at least one of the group is strongly skewed and at least one of the group has an extreme outlier.

Could someone please give detail explanation of the following
graphs. I try to understand what assumptions are being violate here

Could someone check my answers, please? 1. Suppose that a species of fish has split into two populations in a lake: one on the eastern side and one on the western side. How could you determine whether the two populations constitute different species? A. Examine the populations for morphological, color, or other physical differences. B. Examine the populations for different genetic markers and allele frequencies. C. Attempt to breed members from the two populations in captivity. D. Introduce members from...
