Mode: Specifies which alternative hypothesis to use:
•
1: π < π
0
• 2: π > π
0
• 3: π ≠ π
0
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
