Business Discuss
You want to obtain a sample to estimate the proportion of a population that possess a particular genetic marker.  Based on previous evidence, you believe approximately p∗=11% of the population have the genetic marker.  You would like to be 90% confident that your estimate is within 0.5% of the true population proportion.  How large of a sample size is required?n =       (Wrong: 10,603) Do not round mid-calculation. However, you may use a critical value accurate to three decimal places.
