This is a two-tailed test, so we need to split the significance level in half to get α/2 for each tail. We also use a standard normal distribution since the sample size is large enough to approximate the population distribution. Therefore, the appropriate critical values are ± zα/2, where zα/2 is the z-score corresponding to α/2.
