I'd say T is the random variable with a Student distribution under the
null, and t is the observed value of the test statitic

What are the capital Ts in the results printed out after using ttest, e.g.,
Pr(T< t), Pr(|T|> |t|), or Pr(T> t)
for the one-tailed and two-tailed HAs? I interpret the p values as the probability that the sample mean came from the null sampling distribution, but what is the English for Pr(T> t)?
Thanks.
