# Question: Suppose that you have been hired to estimate the percentage

Suppose that you have been hired to estimate the percentage of adults in your state who are literate. You take a random sample of 100 adults and find that 96 are literate. You then obtain a 95% confidence interval of 0.96 ± 1.96 · √(0.96)(0.04)/100, or 0.922 to 0.99

8. From it you conclude that you can be 95% confident that the percentage of all adults in your state who are literate is somewhere between 92.2% and 99.8%. Is anything wrong with this reasoning?
