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. WebTwo Means Z-test Calculator This calculator allows to run a z-test for two means, showing all the steps. The z-test is very similar to a t-test, but with a clear difference that for the case of a z-test we need to know the corresponding population standard deviation.. For this test you need to provide two samples, plus the corresponding population standard deviation …
