1-PropZInt (one-proportion z confidence interval; item A) 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.

2-PropZInt (two-proportion z confidence interval; item B) computes a confidence interval
for the difference between the proportion of successes in two populations (p1Np2). It
takes as input the count of successes in each sample (x1andx2) and the count of
