HP Prime Graphing NW280AAABA manual HypT2meanx1,x2,s1,s2, n1,n2, α,pooled,mode

Mode: Specifies which alternative hypothesis to use:

•1: μ < μ0

•2: μ > μ0

•3: μ ≠ μ0 Example:

HypT1mean(0.461368, 0.2776, 50, 0.5, 0.05, 1) returns {1, -.9462…, 0.4614, 0.8277…, 1.6448…, 0.5671…}

HypT2mean The two-sample T-test for means. Returns a list containing (in order):

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

•The test T-value

•The test Δ x value

•The upper-tail probability

•The degrees of freedom

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

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

HypT2mean((x1,x2,s1,s2, n1,n2, α,pooled,mode)

Pooled: Specifies whether or not the samples are pooled

•0: not pooled

•1: pooled

Mode: Specifies which alternative hypothesis to use:

•1: μ1 < μ2

•2: μ1 > μ2

•3: μ1 ≠ μ2 Example:

HypT2mean(0.461368, 0.522851, 0.2776, 0.2943,50, 50, 0.05, 0, 1) returns {1, -1.0746…, -0.0614…, 0.8574…, 97.6674…, 1.6606…, 0.0335…}
