The two-tailed p-value is P > |t|. This can be rewritten as P (>3.7341) + P (< -3.7341). Because the t-distribution is symmetric about zero, these two probabilities are equal: P > |t| = 2 * P (< -3.7341). Thus, we can see that the two-tailed p-value is twice the one-tailed p-value for the alternative hypothesis that (diff < 0).

If you are using a significance level of.05, a one-tailed test allots all of your alpha to testing the statistical significance in the one direction of interest. This means that.05 is in one tail of the distribution of your test statistic.
