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
