Command Syntax
“Prop condition”, p0 value, x value, n value
Definition of Terms
Prop condition: sample proportion test condition (“≠” specifies two-tail test, “<”
specifies lower one-tail test, “>” specifies upper one-tail test.)
p0 : expected sample proportion (0 < p0 < 1)
x : sample value (integer, x > 0)
n : sample size (positive integer)
Input Example:
OnePropZTest “≠”,0.5,2048,4040
Calculation Result Output
