1. A study was conducted to determine the true proportion of overweight housed cats. Previous studies have concluded that 60% of household
cats are overweight. To be accurate within 5% of the true proportion at a 99% confidence level, how many cats must we survey?
2. This question comes from chapter 8 about finding minimum sample sizes to estimate population proportions.
3. I think this could make a good test question as it requires sufficient knowledge of the equations from chapter 8, and a good understanding of
how to interpret a question to determine what equation must be used.
