HP Prime Graphing NW280AAABA manual Inference app functions, SetIndep, DoInference, HypZ1mean

SetIndep	Set independent column. Sets the independent column for one
	of the statistical analyses S1-S5to one of the column
	variables C0-C9.
	SetIndep(Sn,Cn)
	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 x 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( x, n,μ0,σ,α,mode)

Mode: Specifies which alternative hypothesis to use:

•1: μ < μ0

•2: μ > μ0

•3: μ ≠ μ0
