We wish to estimate what percent of adult residents in Ventura County like chocolate. Out of 300 adult residents sampled, 270 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? Confidence Interval for a Population Proportion One-Way ANOVA Two Independent Proportions Comparison Two Independent Sample Means Comparison Given Statistics Two Dependent Sample Means Comparison Given Data Chi-Square Test for Independence Chi-Square Test for Goodness of Fit Two Independent Sample Means Comparison Given Data Confidence Interval for a Population Mean Given Statistics Hypothesis Test for a Population Mean Given Statistics Hypothesis Test for a Population Proportion Hypothesis Test for a Population Mean Given Data Confidence Interval for a Population Mean Given Data A.  Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents)…

If we find a 95% confidence interval using a sample, then we can say... 95% of individuals will fall on that interval there is a 5% chance the population proportion is NOT on the interval. 95% of our samples will fall on that interval. No answer text provided.

You are interested in finding a 98% confidence interval for the average commute that non-residential students have to their college. The data below show the number of commute miles for 11 randomly selected non-residential college students. Round answers to 3 decimal places where possible.   18 18 27 17 15 7 11 15 9 12 19 a. With 98% confidence the population mean commute for non-residential college students is between _____  and____miles. b. If many groups of 11 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About (____)  percent of these confidence intervals will contain the true population mean number of commute miles and about(_____)   percent will not contain the true population mean number of commute miles.
