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
random variable is greater than value.
VTPC(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.
\]TPF{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.
VTPN{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.
\JTPT{degrees,value)
