zInterval_2Prop

x1 n1 x2
zInterval_2Prop , ,
Computes a two-proportion z confidence interval. A summary of
results is stored in the stat.results variable. (See page 97.)
x1 and x2 are non-negative integers.
For information on the effect of empty elements in a list, see "Empty
(void) elements" on page 131.
