Answer:
B. The width of the confidence interval would be smaller.
Step-by-step explanation:
By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.
Therefore, the answer is B. The width of the confidence interval would be smaller.
