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)?
