Functions and commands
HypZ1mean
The one-sample Z-test for a mean.
HypZ1mean( , n,
0
,,,mode, [”configuration”])
The input parameters can be a range reference, a list of cell
references, or a simple list of values.
Mode: Specifies which alternative hypothesis to use:
•
1: <
0
•
2: >
0
•
3: ≠
0
Configuration: a string that controls what results are shown
and the order in which they appear. An empty string ""
displays the default: all results, including headers. The options
in the configuration string are separated by spaces.
•
h: header cells will be created
•
acc: the test result, 0 or 1 to reject or fail to reject the null
hypothesis
•
tZ: the test Z-value
•
tM: the input value
•
prob: the lower-tail probability
•
cZ: the critical Z-value associated with the input α-level
•
cx1: the lower critical value of the mean associated with
the critical Z-value
•
cx2: the upper critical value of the mean associated with
the critical Z-value
•
std: the standard deviation
Example:
HypZ1mean(0.461368, 50, 0.5, 0.2887, 0.05, 1,
