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.
1 (List)c2(<)c
bb.fw
dw
1 (List1)c1(1)c
1 (CALC)
µ<11.5 ............ assumed population mean and direction of test
z ...................... z value
p ..................... p-value
o ..................... sample mean
x σ
n -1
................ sample standard deviation
n ..................... sample size
6 (DRAW) can be used in place of 1(CALC) in the final Execute line to draw a
graph.
