A pooled estimate of variance is used for the statistic. In the one sample case the distribution under the null hypothesis is a central t with n-1 degrees of freedom. In the two sample cases with sample sizes n and m not necessarily equal the null distribution of the test staistics is t with n+m-2 degrees of freedom.
 It allows us to determine the sample size required to detect an effect of a given pwr.t.test(n = , d = , sig.level = , power = , type = c("two.sample", "one.sample",
