A toy store would like to open a new store in the city of Thousand Oaks, and they would like to know whatproportion of households have kids. Out of 100 households sampled, 49 had kids. Based on this, toconstruct a 99% confidence interval for the true population proportion of Thousand Oaks households withkids, you need to use which one of the following calculators?O Two Independent Sample Means Comparison Given DataO Chi-Square Test for IndependenceO Confidence Interval for a Population Mean Given StatisticsO Two Independent Sample Means Comparison Given StatisticsO Hypothesis Test for a Population Mean Given DataO Chi-Square Test for Goodness of FitO Confidence Interval for a Population ProportionO One-Way ANOVAO Hypothesis Test for a Population ProportionO Confidence Interval for a Population Mean Given DataO Two Dependent Sample Means Comparison Given DataO Hypothesis Test for a Population Mean Given StatisticsO Two Independent Proportions Comparisona. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate tothree decimal places.Confidence interval=b. Express the same answer as a tri-linear inequality using decimals (not percents) accurate to threedecimal places.
