If you obtain 0 successes or n successes when using n trials to estimate a population proportion, our formula for a 95% confidence interval breaks down and has a width of 0. In these situations, the formulas in Module4Quiz_Blyth.xlsx enable us to compute 95% confidence intervals for a population proportion.
