In a test of a particular weight loss program, weights of 40 subjects are recorded before and after the program. The before-and-after weights result in a correlation coefficient of 0.876. Assuming a 0.05 significance level, find the critical values. Is there sufficient evidence to support the claim of a linear correlation between before-and-after weights?

I just took the quiz, the answer is A: Critical values=0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights.

A- 0.312 there is

B - 0.561

D - 0.254

A - 0.917 there is

A - .707 there is NOT

A - 0.918

A - 0.765

B - -0.992

B - 0.985, crit= 0.917

C - 0.867, crit= 0.878
