For a two-sided test, we need to consider both tails of the distribution. The P-value for a one-sided test represents the area in only one tail of the distribution. Thus, for a two-sided test, we need to double the one-sided P-value to get the combined area of both tails. Therefore, the P-value for the two-sided test would be 0.02 x 2 = 0.04.
