A polling agency obtains a list of telephone numbers for 100,000 registered voters in a community. From these numbers the agency randomly selects 900 individuals to participate in a brief survey (you may assume for the sake of this question that all contacted individuals respond). One of the questions asked is the respondent's age. A month later, the agency conducts a similar survey, but contacts only 400 individuals. Which statement below is true? Question 8 options: The 95% confidence interval for age will be narrower (more precise) in the first survey than in the second survey, since the sample size was larger for the first survey. The 95% confidence interval for age will be wider (less precise) in the first survey than in the second survey, since the sample size was larger for the first survey. The 95% confidence intervals for age should be the same width for both surveys, since the polling agency is sampling from the same population in both cases. If the polling agency were to construct 95% confidence intervals thousands of times, they would capture the true population mean only about 5% of the time
