Discussion #1
In a test of a weight loss program, weights of 40 subjects are recorded before and after the program. Assume that the before/after weights result in r = 0.876.
Is there sufficient evidence to support a claim of a linear correlation between before/after weights?
Does the value of r indicate that the program is effective in reducing weight? Why or why not?
Comment on your classmates postings by comparing and contrasting your results.
Discussion #2
In keeping with the environmental concerns this week, discuss your initial reaction to the following statement.
"Eventually, all species become extinct. Thus, it does not really matter that the passenger pigeon is extinct and that the whooping crane and the world's remaining tiger species are endangered mostly because of human activities."
Do you agree or disagree with this? Why or why not?
Do you feel the Endangered Species Act should be strengthened or weakened? Explain.
