The following shows the meaning of each item in the case of list data specifica-
tion.
Data ................ data type
µ
..................... population mean value test conditions (“
G
µ
0
” specifies
two-tail test, “<
µ
0
” specifies lower one-tail test, “>
µ
0
”
specifies upper one-tail test.)
µ
0
.................... assumed population mean
σ
..................... population standard deviation (
σ
> 0)
List .................. list whose contents you want to use as data (List 1 to 6)
Freq ................ frequency (1 or List 1 to 6)
Execute .......... executes a calculation or draws a graph
The following shows the meaning of parameter data specification items that are
different from list data specification.
o
..................... sample mean
n
..................... sample size (positive integer)
Example To perform a 1-Sample
Z
Test for one list of data
For this example, we will perform a
µ
<
µ
0
test for the data List1
= {11.2, 10.9, 12.5, 11.3, 11.7}, when
µ
0
= 11.5 and
σ
= 3.
