Solution

Lowering the Confidence Level will make the Confidence Interval get smaller. This is because the confidence level represents the degree of certainty we have that the true population parameter lies within the confidence interval. If we decrease the confidence level, we are accepting a higher probability that the true population parameter may not lie within the confidence interval, thus the interval gets smaller.
