zInterval_2Prop x1,n1,x2,n2[,CLevel]
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.
Output variable Description
stat.CLower, stat.CUpper Confidence interval containing confidence level probability of distribution
stat.Ç Diff
The calculated difference between proportions
stat.ME Margin of error
stat.Ç1
First sample proportion estimate
stat.Ç2
Second sample proportion estimate
stat.n1 Sample size in data sequence one
stat.n2 Sample size in data sequence two
