We wish to estimate what percent of adult residents in Ventura County like chocolate. Out of 400 adult residents sampled, 349 like chocolate. To construct a 95% 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? O Two Dependent Sample Means Comparison Given Data Confidence Interval for a Population Mean Given Data O Confidence Interval for a Population Proportion O Hypothesis Test for a Population Mean Given Data O Chi-Square Test for Goodness of Fit O Confidence Interval for a Population Mean Given Statistics O Hypothesis Test for a Population Proportion OTwo Independent Sample Means Comparison Given Statistics O Chi-Square Test for Independence OTwo Independent Proportions Comparison O One-Way ANOVA O Two Independent Sample Means Comparison Given Data Hypothesis Test for a Population Mean Given Statistics a. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. Confidence interval= b. Express the same answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.
