Is college worth it?: A poll was conducted to determine why Americans decide not to go to college. Of the 322 Americans who didn't go to college survey surveyed, 46% decided not to go to college because they couldn't afford it. a) Calculate a 90% confidence interval for the proportion of Americans who decide to not go to college because they couldn't afford it, and interpret the interval in context. Round your answers to 4 decimal places. lower bound: 0.5057 upper bound: 0.4143 Interpret the confidence interval in context: We are 90% confident that our confidence interval contains the sample proportion of Americans who choose not to go to college because they cannot afford it We are 90% confident that the proportion of all Americans who choose not to go to college because they cannot afford it is contained within our confidence interval 90% of Americans choose not to go to college because they cannot afford it b) 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. A survey should include at least people.
