Hello,
Hopefully my screenshot is visible! Studying for the CQE and looking through the primer, and I am getting hung up on a few parts of this page.
1) the total observed variation is found to be 0.881 based on the 0.701 sigma_proc and 0.534 sigma_meas. Fine that makes sense. But then it says "the measurement error constitutes a substantial portion of the total observed variation- about 37%". Where does that come from? Sigma_observed=0.881, and 0.534 is not 37% of that figure...
2) for the final sentence where it says "obviously the 49% consumed by the measuring system is too large" - what would be acceptable, 30%?
