Description: Tests a hypothesis relative to a population mean when population standard
deviation is known. A 1-Sample
Z Test is used for normal distribution.
Z =
o –
0
σ
µ
n
o
: mean of sample data
µ
0
: assumed population mean
σ
: population standard deviation
n
: sample size
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”,
µ
0
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:
Syntax 1 (list format)
OneSampleZTest “
≠
”,0,1,list1,1
Syntax 2 (parameter format)
OneSampleZTest “
