Performs a one-sample t-test or t-confidence interval for the mean.
Use 1-Sample t to compute a confidence interval and perform a hypothesis test of the mean when the population standard deviation, s, is unknown. For a two-tailed one-sample t,
H0: m = m 0 versus H1: m ≠ m 0
where m is the population mean and m 0 is the hypothesized population mean.
