The following shows the meaning of each item in the case of list data specification.
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
List .................. list whose contents you want to use as data
Freq ................ frequency
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
x
σ
n -1
................ sample standard deviation (
x
σ
n -1
> 0)
n
..................... sample size (positive integer)
