Answer:
The shorter range.
Step-by-step explanation:
When you think about the confidence interval you automatically think about how wide it is, in relation to its range. A typical confidence interval is generally 95%, however when it increases, it also increases the 'confidence' of the data and therefore its range.
Logically, a level of confidence of 85% will be much narrower than one of 90%, 95% or 99%, this implies that the wide range will be narrower than that of others. So things the 85% confidence interval in a multiple selection response, compared to the other three intervals, will always be the shortest.
