This test uses the hypothesis test for a single unknown population mean when the population standard deviation is unknown. The

The following shows the meaning of each item in the case of list data specification.
Data ............................ | data type |
∝ .................................. | population mean value test conditions (“G∝0” specifies two- |
| tail test, “< ∝0” specifies lower |
| upper |
∝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 specification items that are different from list data specification.
o .................................. | mean of sample |
sample standard deviation | |
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.
• 1(CALC) ... Performs the calculation.
• 6(DRAW) ... Draws the graph.
