S x y.

So, if you can find sxx s x x, you could calculate sxy = msxx s x y = m s x x, and then syy = m2sxx r2 s y y = m 2 s x x r 2. And you're given m = −2.367 m = − 2.367 and r2 = 0.3392 r 2 = 0.3392. I'm having trouble figuring out a way to get sxx s x x, though. Share. Cite. Follow. answered May 31, 2022 at 17:05.
