of the statistical analyses S1-S5 to one of the column

variables C0-C9.

Example:

SetIndep(S1, C2) sets the

Independent Column

field for the S1 analysis to use the data in list C2.

Inference app functions

The Inference app has a single function that returns the same

results as tapping

in the Numeric view of the Inference

app. The results depend on the contents of the Inference app

variables Method, Type, and AltHyp.

DoInference Calculate confidence interval or test hypothesis. Uses the

current settings in the Symbolic and Numeric views to

calculate a confidence interval or test an hypothesis. Performs

the same calculations as tapping in the Numeric view

of the Inference app and stores the results in the appropriate

Inference app results variables.

DoInference()

HypZ1mean The one-sample Z-test for a mean. Returns a list containing (in

order):

• 0 or 1 to reject or fail to reject the null hypothesis

• The test Z-value

• The input value

• The upper-tail probability

• The upper critical Z-value associated with the input α-level

• The critical value of the statistic associated with the

critical Z-value

HypZ1mean( , n,

,,,mode)

Mode: Specifies which alternative hypothesis to use:

• 1:  < 

• 2:  > 

• 3:  ≠ 
