Functions and commands

prob: the lower-tail probability

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

cp1: The lower critical value of  associated with the
critical Z-value

cp2: The upper critical value of  associated with the
critical Z-value

Example:

HypZ2prop(21, 26, 50, 50, 0.05, 1, "")

HypT1mean

The one-sample t-test for a mean.

HypT1mean( ,s,n,

0

,mode,[”configuration”])

Mode: Specifies which alternative hypothesis to use:

1:  < 

0

2:  > 

0

3:  ≠ 

0

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 value

prob: the lower-tail probability

df: the degrees of freedom

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

cx1: the lower critical value of the mean associated with
the critical T-value

cx2: the upper critical value of the mean associated with
the critical T-value

Example:

HypT1mean(0.461368, 0.2776, 50, 0.5, 0.05, 1,
"")
