An economist at the Florida Department of Labor and Employment needs to estimate the unemployment
rate in Okeechobee county. The economist found that 4.6% of a random sample of 529 county residents
were unemployed.
Find three different confidence intervals for the true proportion of Okeechobee county residents who are
unemployed. Calculate one confidence interval with a 90% confidence level, one with a 95% confidence
level, and one with a 96% 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
• The margin of error for a 95% confidence interval is given by E =
A 95% confidence interval is given by
• The margin of error for a 96% confidence interval is given by E =
A 96% confidence interval is given by
