order):

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

• The test Z-value

• The test Δ value

• The upper-tail probability

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

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

value

HypZ2mean( , , n

Mode: Specifies which alternative hypothesis to use:

• 1: μ

< μ

• 2: μ

> μ

• 3: μ

≠ μ
