Vlad the Impaler promotes many of his soldiers into generals (don't ask what happened to the past generals). Vlad was told by his informers that the proportion is about 62%, but wants to estimate the proportion better by sampling soldiers until her margin of error for a 97% Confidence Interval is less than 0.007. How many soldiers should Haley sample? Now assume that the proportion 62% was not known to Vlad. Vlad wants to estimate the proportion better by sampling soldiers until her margin of error for a 97% Confidence Interval is less than 0.007. How many soldiers should Haley sample?
