Methods · interval estimates for proportions · manipulative
Each sample builds its own width from p̂(1−p̂). Most intervals cover the true p — but not all, and skinny extreme samples miss more often.
Dashed line is p · bar length = that sample’s MoE · grow the bank or change p / n / level
How many CIs on the plot. Widths differ because each sample has its own p̂.
Changing p redraws samples. n recomputes each p̂ from stored Bernoulli draws; level only resizes widths.
