The confidence level represents the likelihood that the true population parameter falls within a certain range. Therefore, as the confidence level increases, the range or interval that contains the parameter must be wider to accommodate a greater degree of uncertainty. This means that choice B, which states that the confidence interval is wider, is the correct answer.
