An analyst is conducting a survey to measure height. Which of the following is the most likely to decrease as the analyst collects more survey responses?

The correct answer is D. The confidence interval. The confidence interval (CI) represents the range within which a population parameter is estimated to fall. As the sample size increases, the margin of error shrinks, causing the confidence interval to become narrower (decrease in width). The mean may fluctuate but doesn't…

Explanation

The confidence interval (CI) represents the range within which a population parameter is estimated to fall. As the sample size increases, the margin of error shrinks, causing the confidence interval to become narrower (decrease in width). The mean may fluctuate but doesn't consistently decrease. Sample size increases as more responses are collected, not decreases. The population is fixed and unaffected by survey responses. Therefore, the confidence interval is the metric most likely to decrease as more survey responses are collected.
