Variables Used:
D Dummy variable of integration.
M Population mean, default value zero.
Q Probability corresponding to the upper-tail area.
S Population standard deviation, default value of 1.
T Variable used temporarily to pass the value S\/2ir to the inverse
program.
X Input value that defines the left side of the upper-tail area.
Example 1. Your good friend informs you that your blind date has
"3<t" intelligence. You interpret this to mean that this person is more
intelligent than the local population except for people more than
three standard deviations above the mean. Suppose that you intuit
that the local population contains 10,000 possible blind dates. How
many people fall into the "3a" band? Since this problem is stated in
terms of standard deviations, use the default values of zero for M and
1 for S.

Display: Description:
M70.0000
Starts the initialization
routine.
S71.0000
Accepts the default
value of zero for M.
1.0000
Accepts the default
value of 1 for S.
X?value Starts the distribution
program and prompts
for X.
Q=0.0014
Enters 3 for X and
starts computation of
Q(X). Displays the ra
