Flags Used:

None.

Remarks:

The accuracy of this program is dependent on the display setting. For inputs in the area between ±3 standard deviations, a display of four or more significant figures is adequate for most applications.

At full precision, the input limit becomes ±5 standard deviations. Computation time is significantly less with a lower number of displayed digits.

In routine Q, the constant 0.5 may be replaced by 2 and .

You do not need to key in the inverse routine (in routines I and T) if you are not interested in the inverse capability.

Program Instructions:

1.Key in the program routines; press ‡when done.

2.Press XS.

3.After the prompt for M, key in the population mean and press g. (If the mean is zero, just press g.)

4.After the prompt for S, key in the population standard deviation and press g. (If the standard deviation is 1, just press g.)

5.To calculate X given Q(X), skip to step 9 of these instructions.
