Question

Quizplus · Accepted Answer

To find the z statistic from a normal distribution table for a two-tailed test with an alpha level of .1388, we need to find the critical z value that leaves .0694 in each tail (since it is a two-tailed test, the total alpha level is split between both tails). Looking up the closest value to .0694 in the z-table gives us a z value of 1.48.
