Page 381: The solution for Example 6.16 has \(P \dot\sim N\left(0.383, \sqrt{\tfrac{(0.383)(0.617)}{250}} = 0.0019 \right).\) The solution should read:
\[P \dot\sim N\left(0.383, \sqrt{\tfrac{(0.383)(0.617)}{250}} = 0.0307 \right)\]

ggplot_hline(y = value) appears now needs to be
ggplot_hline(yintercept = value)
