WebLeft-tail critical value: 1 – (0.05 / 2) = 0.975. In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833.

WebThe critical values come from the same z-table we used from Chapter 6. Since the confidence level is 99%, we have α=0.01 and α/2=0.012=0.005. This means that on the normal curve, there is an area of 0.01 in both tails, and 0.005 in a single tail. Using either the table or invnorm(0.005, 0, 1), we get a critical value of zα/2≈±2.575. 4.
