Suppose the survey in the previous exercise also asked those who were not in the top 1% whether they believed that within 5 years they would be in the top 1% (1 = will not be in top 1% within 5 years and 2 = will be in top 1% within 5 years). Estimate with 95% confidence the number of Americans who believe that they will be in the top 1% of income earners within 5 years.
