... The 0.05 significance level is to be used. The alternate hypothesis does not state a direction, so this is a two-tailed test. The 0.05 significance level is divided equally into two tails of the standard normal distribution. Hence, the area in the left tail is 0.0250 and the area in the right tail i ...
