At her job, Jackie has been working at her job for a few years now and feels like she, as well as everybody else in her department, is well overdue for a raise. Instead of collecting signatures of her colleagues in support of a pay raise, her boss sends out a poll to all employees in all departments to get a feel for what the others think. Assuming Jackie's boss wants only a 5% margin of error and a 99% confidence interval, what sample size is needed? Even though nobody that works there is not missing half of their body, it is okay if the sample size needed includes a decimal.
