Suppose your boss wants you to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the value of the population proportion. You would Like to be 90% confident that your estimate is within 2.5% [0.02 5} of the true population proportion. What is the minimum sample size required? 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-offany other intermediate results. n
