HypT2mean The two-sample T-test for the difference of two means.

HypT2mean((x1,x2,s1,s2, n1,n2, α,pooled,mode, [”configuration”])

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

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

•tT: the test T-value

•tM: the input Δ x value

•prob: the lower-tail probability

•cT: the critical T-value associated with the input α-level

•cx1: the lower critical value of Δ x associated with the critical T-value

•cx2: the upper critical value of Δ x associated with the critical T-value

Example:

HypT2mean(0.461368, 0.522851, 0.2776, 0.2943,50, 50, 0, 0.05, 1, "")

ConfZ1mean The one-sample Normal confidence interval for a mean.

ConfZ1mean( x ,n,s, C,[”configuration”])

Configuration is 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.
