The p-value for a one-sided test is half of the two-sided test if the direction of the one-sided test aligns with the alternative hypothesis suggested by the data. However, if the direction is opposite, the p-value would be 1 minus half of the two-sided p-value. Therefore, it depends on the direction of the alternative hypothesis.
