Critical values for Confidence Intervals

[@hannahkraiter7722]

I have been struggling with this concept so much - you are a lifesaver.

[@stephanefarley1898]

Thank you for explaining, as no other can kiss you!

[@Stepho-xb1cm]

Thank you! I had been looking at tons of videos and this one helped me the most to understand what I am suppose to do.

[@Armyprincess1974]

Thank you so much for this video! My statistics professor just does not have the ability to demonstrate how to do this function.

[@erinm5711]

YOU ARE THE BEST!!!!!!!!!! thank you for this tutorial!!!!!!!!

[@andrewmcmanus3481]

Thank you for this video!

[@cristinavega475]

Thank you very much, this was incredibly helpful, especially at this moment in time.

[@amyortiz1216]

this video is so clear and easy to understand. Thanks for the help!!!!!!!!!!!!!

[@WSGFunChannel]

You should search for videos on how to do it with the calculator you do have, or search for videos that use the Z, T, chi-square, etc. TABLES. This video was made for students in my class where the calculator was a requirement.

Still helpful to this day 😃

[@Msarijana05]

thanks!

[@kpowers511]

thank you

[@sklorbit]

Thank you! Very helpful

[@yessy804]

omg thank you. i did went to class when the professor taught this topic but i did not get it.

[@florenceallbaugh9809]

AHHh. This was excellent. Now I get it.

[@Sophia-wq1gi]

On a TI 83, how do you get to "InvNorm"?

[@TheHOTchocolate911]

thanks for this video! my teacher sucks :)

[@masquereseau5635]

How do you find a confidence level with a given t value? Ti nspire can't solve (invt(x,15)=2.7,x) for example.

[@WSGFunChannel]

I'm not 100% certain I understand. Do you know the sample size (or degrees of freedom)? If so you could possibly use tcdf(-t,t,df) if the t you're referring to is the upper critical t.

[@masquereseau5635]

+David Blevins yes exactly i found out it was tcdf by digging in my textbook. thanks

[@studentzombie279]

so confused...

[@stephenprice3357]

wish the video taught how to do it without calculator

[@MrDaveblev]

Stephen Price using tables? Find the closest number you could find to 0.0200 within the table. Then look left and up to see the z score.

thanks!
