From the author's description:

	t-test performs the Student's t-test statistical test between
	two population or sample means.  A brief help screen is accessed
	by clicking the "about" balloon in the upper right corner of the
	stack's main card.  t-test is in the HyperCard 1.2 format so if
	you have a newer version you must convert the stack in order to
	use it.  HyperCard automatically asks you to do this when you
	begin.

One- or two-tailed tests assuming variances are equal or unequal are
computed after the means, n, and one of variance or standard deviation
are entered.  The resut displays the t-value, the degrees of freedom,
the p-value and the significance level.

Tested using HyperCard 2.3 with no problems.
