A random sample conducted by the Martin County Economic Development Board found that 33.1% of all county residents held at least a bachelor's degree. Find three different confidence intervals - one with sample size 188, one with sample size 461, and one with sample size 852. Assume that 33.1% of the county residents in each sample have earned at least a bachelor's degree. Notice how the sample size affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Report all solutions in percent form, rounded to two decimal places, if necessary. . When n = 188, the margin of error for a 97% confidence interval is given by When n = 188, a 97% confidence interval is given by . When n = 461, the margin of error for a 97% confidence interval is given by When n = 461, a 97% confidence interval is given by . When n - 852, the margin of error for a 97% confidence interval is given by
