| Since its a 5% level of confidence, you know that your positive test stat will lie at the high end of the distribution at 0.975 (100%-5%/2=97.5%). You use the chart to find the 0.975 and it corresponds to the 1.9 row and 6 (or .06, I can’t remember) column, which means your test stat is 1.96. But if you know that off the top of your head, all the better. CFA just doesn’t expect you to memorize the Z-chart so they provide you with it.
