So here is the methodology: 1. Hit the site above. 2. Randomly pick a company from the list... for instance: 3. Pick Paychex Systems... company 921 on Fortunes list... 4. On their site they list 137 job openings... 5. Add that to the total... 6. Repeat until you have a representative sample size

Question: Using an appropriate random number generation between 1 and 1000, what is the sample size required to then estimate the total job openings on the 1000 sites?
