(y). It displays values for a and b; it
also displays values for r
2
and r.
% u " displays the DISTR menu, which
has the following distribution functions:
1: Normalpdf Computes the probability density
function (pdf) for the normal
distribution at a specified x value.
The defaults are mean mu=0 and
standard deviation sigma=1. The
probability density function (pdf) is:
2: Normalcdf Computes the normal distribution
probability between LOWERbnd
and UPPERbnd for the specified
mean mu and standard deviation
sigma. The defaults are mu=0;
sigma=1; with LOWERbnd = M1E99
and UPPERbnd = 1E99. Note: M1E99
to 1E99 represents Minfinity to infinity.
3: invNorm Computes the inverse cumulative
normal distribution function for a
given area under the normal
distribution curve specified by mean
mu and standard deviation sigma. It
calculates the x value associated
with an area to the left of the x value.
0{area{1 must be true. The
defaults are area=1, mu=0 and
sigma=1.
