• Executing DrawDistNorm performs the above calculation
in accordance with the specified conditions and draws
the graph. At this time the ZLow
 x  ZUp region on the
graph is filled in.
• At the same time, the p , ZLow, and ZUp calculation result values are assigned respectively to
variables p , ZLow, and ZUp, and p is assigned to Ans.

• Executing DrawDistT performs the above calculation in accordance with the specified
conditions and draws the graph. At this time the Lower  x  Upper region on the graph is
filled in.
• At the same time, the p calculation result value and the Lower and Upper input values are
assigned respectively to variables p , tLow, and tUp, and p is assigned to Ans.
