A six sigma projection manager should infer the formulas and computations within the most commonly practical tests.
But, for the t-test, the middle-aged excel function =tinv for the one-tail significance testing has been found to be a number awkward, because this function giving the t-value has taken that it is a two-tail chance in its algorithmic program.
