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

•tZ: the test Z-value

•tP: the test proportion of successes

•prob: the lower-tail probability

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

•cp1: the lower critical proportion of successes associated with the critical Z-value

•cp2: the upper critical proportion of successes associated with the critical Z-value

•std: the standard deviation

Example:

HypZ1prop(21, 50, 0.5, 0.05,1, "")

HypZ2prop The two-sample Z-test for comparing two proportions.

HypZ2prop(x1,x2,n1,n2,α,mode,

[”configuration”]) where x1 and x2 are the success counts of the two samples)

Mode: Specifies which alternative hypothesis to use:

•1: π1 < π2

•2: π1 > π2

•3: π1 ≠ π2

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

•tZ: the test Z-value

•tP: the test Δπ value
