Final Answer

Thank you for the opportunity to help you with your question!

Higher confidence levels have a wider confidence intervals.


1.It is always higher than lower confidence levels (all other things being equal).

2.Confidence Interval = Sample Mean +/- (Critical Value) * Sample Standard Deviation / SQRT (Sample Size)

(Critical Value) is "curve" whose distribution depends on Confidence Level. Higher Confidence Level is "farther out" on the "curve" which increases the (Critical Value). Increasing (Critical Value) makes wider Confidence Interval.

Please let me know if you need any clarification. I'm always happy to answer your questions.
