Confidence Interval vs Confidence Level || The difference and how to use them 

Marvelous explanation.

Confidence level is the probability/ likelihood of falling our sample estimate within a range whereas confidence interval is that range.

Oh my god I can't express my appreciation for your great explanation...

Thank you! Very helpful!!

It is better if you explain it in excel sheet by sharing the excel sheet screen

Thank you so much!

When textbook says "measurements are drawn from populations with the same population standard deviation" does it mean measurements drawn from the same "confidence interval"?
