Why am I observing non-uniformly distributed (negatively skewed) p-values for two-sample tests of mixture distributions when the null is true?
I am interested in generating Gaussian mixture distributions as the null distributions for a series of two-sample test simulations. It is a well established fact that p-values follow a uniform ...

How a two-tailed p-value is calculated for a two-sample t-test
I'm reading Discovering Knowledge in Data by Daniel T. Larose. In the two-sample t-test for difference in means section, there is the following example:
tdata = x-bar(1) - (xbar2)/ sqrt(s^2(1)/n(1)+ ...
