Determining a linear correlation

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?
