HP Prime Graphing NW280AAABA manual Test π value, HypZ2mean x1, x2, n1, n2,σ1,σ2,α,mode

Example:

HypZ1mean(0.461368, 50, 0.5, 0.2887, 0.05, 1) returns {1, -.9462…, 0.4614, 0.8277…, 1.6448…, 0.5671…}

HYPZ2mean The two-sample Z-test for means. Returns a list containing (in order):

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

•The test Z-value

•The test Δ x value

•The upper-tail probability

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

•The critical value of Δ x associated with the critical Z- value

HypZ2mean( x1, x2, n1, n2,σ1,σ2,α,mode)

Mode: Specifies which alternative hypothesis to use:

•1: μ1 < μ2

•2: μ1 > μ2

•3: μ1 ≠ μ2 Example:

HypZ2mean(0.461368, 0.522851, 50, 50, 0.2887, 0.2887, 0.05, 1) returns {1, -1.0648…, -0.0614…, 0.8565…, 1.6448…, 0.0334…}

HypZ1prop	The one-proportion Z-test. Returns a list containing (in order):
	• 0 or 1 to reject or fail to reject the null hypothesis
	• The test Z-value
	• The test π value
	• The upper-tail probability
	• The upper critical Z-value associated with the input α-level
	• The critical value of π associated with the critical Z-value
	HypZ1prop(x,n,π0,α,mode)
