If the confidence level is increased from 90% to 99% for an srs of size n, the width of the confidence interval for the mean ? will: decrease. stay the same. increase. the answer cannot be determined with the information given

increase

Step-by-step explanation:

When we increase the confidence level , we actually increase the error bound.

So , it increases the margin of error.

Therefore , if the confidence level is increased from 90% to 99% for an srs of size n then the width of the confidence interval for the mean increases.

Hence , the correct answer is "increase" .
