Command Syntax
Syntax 1 (list format)
“
µ
condition”,
µ
0
value,
σ
value, List, Freq (or 1)
* “Freq” can be omitted. Doing so sets “1” for “Freq”.
Syntax 2 (parameter format)
“
µ
condition”,

value,
σ
value,
o
value,
n
value
Definition of Terms
µ
condition :
population mean value test conditions (“
≠” specifies two-tail test,
“<”specifies lower one-tail test, “>” specifies upper one-tail test.)
µ
0
:
assumed population mean
σ
:
population standard deviation (
σ
> 0)
List :
data list
Freq :
frequency (1 or list name)
o
:
mean of sample data
n
:
sample size (positive integer)
Input Example:
