Yom do riot 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
W
S.
3. After the prompt for M, key in the population mean and press
f
. (If the
mean is zero, just press
f
.)
4. After the prompt for S, key in the population standard deviation and press
f
. (If the standard deviation is 1, just press
f
)
5. To calculate X given Q(X), skip to step 9 of these instructions.
6. To calculate Q(X) given X,
W
D.
7. After the prompt, key in the value of X and press
f
. The result, Q(X), is
displayed.
8. To calculate Q(X) for a new X with the same mean and standard deviation,
press
f
and go to step 7.
9. To calculate X given Q(X), press
W
I.
10. After the prompt, key in the value of Q(X) and press
f
. The result, X, is
displayed.
11. To calculate X for a new Q(X) with the same mean and standard deviation,
press
f
and go to step 10.
Variables Used:
