Functions and commands 159

Mode: Specifies which alternative hypothesis to use:

• 1: π < π

• 2: π > π

• 3: π ≠ π

Example:

HypZ1prop(21, 50, 0.5, 0.05,1) returns {1,

-1.1313…, 0.42, 0.8710…, 1.6448…, 0.6148…}

HypZ2prop The two-sample Z-test for proportions. Returns a list containing

(in order):

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

• The test Z-value

• The test Δπ value

• The upper-tail probability

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

• The critical value of Δπ associated with the critical Z-value

HypZ2prop(x

,α,mode)

Mode: Specifies which alternative hypothesis to use:

• 1: π

< π

• 2: π

> π

• 3: π

≠ π

Example:

HypZ2prop(21, 26, 50, 50, 0.05, 1) returns {1,

-1.0018…, -0.1, 0.8417…, 1.6448…, 0.0633…}

HypT1mean The one-sample t-test for a mean. Returns a list containing (in

order):

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

• The test T-value

• The input value

• The upper-tail probability

• The degrees of freedom

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

• The critical value of the statistic associated with the

critical t-value
