The U.S. forest service is considering additional restrictions on the number of vehicles allowed to enter Yellowstone National Park. To assess public reaction, the service asks a random sample of 150 visitors if they favor the proposal. Of these, 89 say "Yes." We want to construct a 95% confidence interval to estimate the proportion of all visitors to Yellowstone who favor the proposal, with a margin of error of +/-3%. How many visitors must we sample?

  • 150 visitors
  • 1030 visitors
  • 525 visitors
  • 268 visitors
  • 4120 visitors
