A poll was conducted to determine why Americans decide not to go to college. Of the 335 Americans who didn't go to college survey surveyed, 47% decided not to go to college because they couldn't afford it. Suppose we wanted the margin of error for the 90% confidence level to be about 1.5%. What sample size would you recommend for the survey? Round your answer appropriately.
