The number of years of education of self-employed individuals in the United States has a population mean of 13.6 years and a population standard deviation of 3.0 years. If we survey a random sample of 100 self-employed people to determine the average number of years of education for the sample, Build and interpret a 90% confidence interval for the true number of years of education for self-employed individuals when the sample of 100 has an average of 13.6 years.
