¯x : mean of sample
μ 0 : assumed population mean
x σ n-1 : sample standard deviation
n : size of sample

The following shows the meaning of each item in the case of list data specifi cation.
Data.............................. data type
μ .................................. population mean value test conditions (“G μ 0” specifi es two-
tail test, “< μ 0” specifi es lower one-tail test, “> μ 0” specifi es
upper one-tail test.)
μ 0 ................................. assumed population mean
List ............................... list whose contents you want to use as data (List 1 to 26)
Freq .............................. frequency (1 or List 1 to 26)
Save Res ...................... list for storage of calculation results (None or List 1 to 26)
Execute ........................ executes a calculation or draws a graph
The following shows the meaning of parameter data specifi cation items that are different
from list data specifi cation.
¯x .................................. mean of sample
x σ n-1 ............................. sample standard deviation ( x σ n-1 > 0)
n .................................. size of sample (positive integer)
After setting all the parameters, use c to move the highlighting to “Execute” and then press
one of the function keys shown below to perform the calculation or draw the graph.
