Final Answer :
A
Explanation :
The higher the desired level of confidence, the wider the confidence interval for the mean. This is because as the level of confidence increases, the margin of error also increases, resulting in a wider interval. Conversely, a lower desired level of confidence would require a narrower interval as the margin of error would be smaller.
