One-Sample T-Test

Menu name	T-Test: 1 μ
	This test is used when the population standard deviation is
	not known. On the basis of statistics from a single sample,
	this test measures the strength of the evidence for a
	selected hypothesis against the null hypothesis. The null
	hypothesis is that the sample mean has some assumed
	value, Η0 :μ = μ0.
	You select one of the following alternative hypotheses
	against which to test the null hypothesis:
	H0: μ < μ0
	H0: μ > μ0
	H0: μ ≠ μ0
