H I N T	The setting of Time will be different for each calculator, so
	using RANDSEED(Time) is guaranteed to produce a set of
	numbers which are as close to random as possible. You can set
	the seed using the command RANDSEED.
UTPC
	Upper-Tail Chi-Squared Probability given degrees of
	freedom, evaluated at value. Returns the probability that a χ2
	random variable is greater than value.
	UTPC(degrees,value)
UTPF	Upper-Tail Snedecor’s F Probability given numerator
	degrees of freedom and denominator degrees of freedom (of
	the F distribution), evaluated at value. Returns the probability
	that a Snedecor's F random variable is greater than value.
	UTPF(numerator,denominator,value)
UTPN	Upper-Tail Normal Probability given mean and variance,
	evaluated at value. Returns the probability that a normal
	random variable is greater than value for a normal
	distribution. Note: The variance is the square of the standard
	deviation.
	UTPN(mean,variance,value)
UTPT	Upper-Tail Student’s t-Probability given degrees of freedom,
	evaluated at value. Returns the probability that the Student's t-
	random variable is greater than value.
	UTPT(degrees,value)
