An economist at the Florida Department of Labor and Employment needs to estimate the unemployment rate in Indian River county. The economist found that 4.84% of a random sample of 709 county residents were unemployed. Find three different confidence intervals for the true proportion of Indian River county residents who are unemployed. Calculate one confidence interval with a 90% confidence level, one with a 95% confidence level, and one with a 97% confidence level. Notice how the confidence level affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Express solutions in percent form, rounded to two decimal places, if necessary. The margin of error for a 90% confidence interval is given by E A 90% confidence interval is given by =
