HP Prime Graphing NW280AAABA manual HypZ1mean The one-sample Z-test for a mean

HypZ1mean The one-sample Z-test for a mean.

HypZ1mean( x, n,μ0,σ,α,mode, [”configuration”])

The input parameters can be a range reference, a list of cell references, or a simple list of values.

Mode: Specifies which alternative hypothesis to use:

•1: μ < μ0

•2: μ > μ0

•3: μ ≠ μ0

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

•tZ: the test Z-value

•tM: the input x value

•prob: the lower-tail probability

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

•cx1: the lower critical value of the mean associated with the critical Z-value

•cx2: the upper critical value of the mean associated with the critical Z-value

•std: the standard deviation

Example:

HypZ1mean(0.461368, 50, 0.5, 0.2887, 0.05, 1, "")

HYPZ2mean The two-sample Z-test for the difference of two means.

HypZ2mean( x1, x2, n1, n2,σ1,σ2,α,mode, [”configuration”])
