We wish to estimate what percent of adult residents in Ventura County like chocolate. Out of 600 adult residents sampled, 408 like chocolate. To construct a 90% confidence interval for the proportion (p) of adult residents who like chocolate in Ventura County, you need to use which one of the following calculator? Chi-Square Test for Independence Two Dependent Sample Means Comparison Given Data Chi-Square Test for Goodness of Fit Two Independent Sample Means Comparison Given Data Two Independent Sample Means Comparison Given Statistics One-Way ANOVA Two Independent Proportions Comparison Hypothesis Test for a Population Mean Given Statistics Confidence Interval for a Population Proportion Confidence Interval for a Population Mean Given Statistics Confidence Interval for a Population Mean Given Data Hypothesis Test for a Population Mean Given Data Hypothesis Test for a Population Proportion Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. Confidence interval =    Express the same answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places. < p <    Express the same answer using the point estimate and margin of error.
