Question

Quizplus · Accepted Answer

The objects that influence the spread of a confidence interval are the confidence level, the sample size of both the treated and control groups, the variance in the outcome, and the sample average outcome for the treated group. The sample average outcome for the control group does not directly influence the spread of the confidence interval.
