A researcher randomly samples 100 citizens of Florida and finds that 95 of the citizens are literate. The researcher then finds a 90% confidence interval. Which of the following is false?
Correct Answer: A
The procedure used for confidence intervals assumes that Np' > 5 and that N(1 -p') > 5. Because this is not the case, 100(1 - 0.95) = 5, the researcher cannot conclude with 90% confidence that the percentage of Florida citizens that are literate is between 91.4% and 98.6%.
