Dear all,
I observer a strange behavior of the pvalues of the t-test under the null
hypothesis. Specifically, I obtain 2 samples of 3 individuals each from a
normal distribution of mean 0 and variance 1. Then, I calculate the pvalue
using the t-test (var.equal=TRUE, samples are independent). When I make a
histogram of pvalues I see that consistently the bin of the smallest
pvalues has a lower frequency. Is this a known behavior of the t-test or
it's a kind of bug/random number generation problem?

kind regards,
idaios
