We wish to estimate what percent of adult residents in Ventura County like chocolate. Out of 100 adult residents sampled, 67 like chocolate. To construct a 99% 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? Confidence Interval for a Population Proportion Chi-Square Test for Goodness of Fit Confidence Interval for a Population Mean Given Statistics Two Independent Sample Means Comparison Given Data Confidence Interval for a Population Mean Given Data Two Dependent Sample Means Comparison Given Data Hypothesis Test for a Population Mean Given Statistics Two Independent Proportions Comparison One-Way ANOVA Hypothesis Test for a Population Proportion Chi-Square Test for Independence Two Independent Sample Means Comparison Given Statistics Hypothesis Test for a Population Mean Given Data   a)Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places.
