In 2010, an online security firm estimated that 67% of computer users don't change their passwords very often. Because this estimate may be outdated, suppose that you want to carry out a new survey to estimate the proportion of students at your school who do not change their password. You would like to determine the sample size required to estimate this proportion to within a margin of error of 0.03 with 95% confidence. (a)Using 0.67 as a preliminary estimate for...
