k Calculations Using the TEST Command
You can use special functions in the Run-Matrix mode or Program mode to perform
calculations that are the same as the Statistics mode Z Test, t Test, and other test
calculations (page 6-33).
Example To determine the
z score and p -value when a one-sample Z test is
performed under the conditions below:
test condition (
 condition)
≠

0
*, assumed population mean 
0
= 0,
population standard deviation  = 1, sample mean
o
= 1, number of
samples n = 2
* “
 condition ≠ 
0
” can be specified by entering 0 as the initial argument of
the one-sample Z test command “OneSampleZTest”.
1. From the Main Menu, enter the Run-Matrix mode.
2. Perform the following key operation.
!m(SET UP)2(Line)J
K5(STAT) 6( g) 1(TEST) 1(Z)
1(1-Sample) a,a,b,b
,cw
JJJ
1(LIST) 1(List) !-(Ans) w
The following calculation results are displayed as ListAns elements 1 through 4.
1:
z score
2:
p -value
3: o
4:
n
