  tailed p-value is usually just half of a two tailed p-value. This is the case for the t-test (because the t-distribution is symmetric), but isn’t the case, for example, with Fisher’s Exact test. Whether you report a one - or two -tailed p-value is sometimes debatable (although one -tailed values are falling out of favor).

The tSTAT in the output (T) is –5.18, the exact value we got manually indicating that our calculation of the Satterthwaite approximation was good, and as we expected, the p value is highly significant, therefore as p < a we reject the null hypothesis in ...

  Here, we will focus on the question of sample size: I how large does a sample need to be so that a con dence interval will be no wider than a given size? I how large does a sample need to be so that a hypothesis test will have a low p-value if a certain alternative hypothesis is true? Sample size determination is just one aspect of good design of
