    2. Often, we use a normal approximation when constructing confidence intervals for proportions. This method is simple and easy to employ, but it isn't perfect. Some possible issues one might encounter when using normal approximations are (check all that apply): a) There is no logical explanation for how observed sample proportions could be approximately normal. b) Especially with smaller sample sizes and with small or large sample proportions, it is possible to get upper and lower bounds less than 0...
