A previous study gave (0.11, 0.23) as a confidence interval for p. Find the minimum sample size required to ensure that your estimate (p) will be within 0.01 of p with 99% confidence. IMPORTANT: Use a critical value that you found with your calculator (not from a table), and round it to 3 places after the decimal point before you plug it into a formula and perform your calculations. Do not round-off any other intermediate results. n=
