Z1-α/2- the Z-value where p(x ≥ Z1-α/2)= α/2, right critical value of the two-tailed test. Example, Inverse z-table: Row number 6 (excluding the header) P( x ≤ -1.644854 ) = 0.05, P( x ≥ 1.644854 ) = 0.05, P( x ≤ -1.959964 ) = 0.025, P( x ≥ 1.959964 ...
Z Table Two Tailed Normal Curve: How To Find The Area While you probably already heard about a two tailed normal curve, you may not know what it is or what it is used for. The truth is that a two tailed normal curve is a curve as the name says but there is an area in each one...

Some of the following z-table methods allow you to use a test statistic from a z-test to find thep-value. The procedure for using z-tables to find p-values depends on whether you’re using a one- or two-tailed test. For one-tailed tests, the directionality is also afactor. In the...
Using an alpha of 0.05 with a two-tailed test, we would expect our distribution to look something like this:Here we have 0.025 in each tail. Looking up 1 - 0.025 in our z-table, we find a critical value of 1.96. Thus, our decision rule for this two-tailed test is: If Z is ...

Two rounds of PCR were performed using nested primers as listed in Supplementary Table S3, and Zymo Taq hot start polymerase (ZYMO, cat. no. E2002) to amplify the converted DNA. The purified PCR was ligated into pGEM-T vector (Promega, cat. no. A3600). Sanger sequencing of 15 independ...
Data are shown as means ± SD, and P values are determined by unpaired two-tailed Student’s t-test (d, i–l). The exact P values are shown in the figure. Source data are provided as a Source Data file. Full size image To further evaluate the promoting effect of ZFYVE28 on ...
