ZPin1
This one-proportion Z confidence interval, shown as
computes a confidence interval for an unknown proportion of successes. It takes
as input the count of successes in the sample x and the count of observations in
the sample n. The computed confidence interval depends on the user-specified
confidence level.

This two-proportion Z confidence interval, shown as
computes a confidence interval for the difference between the proportion of
successes in two populations (p
