Final Answer :
A
Explanation :
A wider confidence interval means that the researcher wants to have more confidence that the true population parameter falls within the interval. A higher confidence level leads to a wider confidence interval because the researcher is allowing for more uncertainty. Therefore, a 99% confidence interval would be the best choice for a wider interval.
