A population of trees within a defined neighborhood has a mean leaf length of 3.2 inches. A sample of 20 of these trees has a mean length of 5.3 inches. If SS = 130 for this sample, what is Cohen's d for this example, and what is the strength of the treatment effect, which in this case is growing in a particular neighborhood?

A population of trees within a defined neighborhood has a mean leaf length of 3.2 inches. A sample of 20 of these trees has a mean length of 5.3 inches. If SS = 130 for this sample, what is Cohen's d for this example, and what is the strength of the treatment effect, which in this case is growing in a particular neighborhood? O d = 0.7, which demonstrates medium effect Od = 1.0, which demonstrates large effect Od = 0.8, which demonstrates a large effect O d = 0.3, which demonstrates a small effect
