The critical values for a two-tailed test when α = 0.03 are ±2.17. This is determined by looking at the z table and finding the z-score that corresponds to an area of 0.015 (0.03 divided by 2, since it is a two-tailed test) in both tails. The closest z-score to this area is 2.17, which is why it is the critical value.
