WebSep 9, 2024 · How to find zα/2 using a z table. Suppose we want to find zα/2 for some test that is using a 90% confidence level. In this case, α would be 1 – 0.9 = 0.1. Thus, α/2 = 0.1/2 = 0.05. To find the corresponding z critical value, we would simply look for 0.05 in a z table: Notice that the exact value of 0.05 doesn’t appear in the table, but ... WebFeb 8, 2024 · The APA 6 style manual states (p.117): “ When reporting confidence intervals, use the format 95% CI [LL, UL] where LL is the lower limit of the confidence interval and UL is the upper limit.”. For example, one might report a 95% CI [5.62, 8.31]. Confidence intervals can also be reported in a table.
