The Indian River County Health Department needs to estimate the proportion of all children in the county aged 19-35 months that are completely up to date with all state-recommended immunizations. The Indian River County Health Department found that 74% of a random sample of children in the county aged 19-35 months were completely up to date withall state-recommended immunizations. Find three different confidence intervals - one with sample size 116, one with sample size 320, and one with sample size 663. Assume that 74% of the children each sample are completely up to date with all state recommended immunizations. 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 = 116, the margin of error for a 97% confidence interval is given by When n = 116, a 97% confidence interval is given by • When n = 320, the margin of error for a 97% confidence interval is given by When n= 320, a 97% confidence interval is given by
