Confidence Interval for Proportions using the exact Bliss Method on the TiNspire

When finding Confidence Intervals for Proportions we typically involve the Normal Distribution to create an confidence Interval estimate. However, this method requires the conditions np<5 and n(1-p)<5 to be fulfilled. It is not uncommon to have a large sample size n available which likely disables this method. This is where the Bliss Method comes in… (read more)
