05 Using the TI 84 Calculator to Find Confidence Intervals

[@kitaclysm]

Thank you! My professor just said "use technology to find the answer" but didn't explain how to go about doing so. Thank you so much for this. You've saved my grade.

[@Skyverb]

Same! Taking Stat online and this is one of the worst classes I've had. The book just keeps saying "use technology" without showing the formulas or anything. Like wtf

[@krashx4195]

Using technology is the laziest explanation I have ever seen. They might as well hire me I'll take that job fr. Anything I don't understand I'll just tell them to use technology.

Did we have the same teacher? Lol

awesome video please never use this mic again

[@brianmorrow6010]

very informative, but my ears are bleeding

[@shorttime1351]

SO helpful thank you! Why can't people just teach intuitively like you

[@melissanne90]

@profthacker - I am currently returning to school to earn a master's degree, but failed Statistics twice during undergrad. As statistics came back to haunt me, I was devastated when our classes went online due to COVID-19. While my instructor is fantastic, your videos are helping me understand the pieces I couldn't! Thank you so so so much for helping me learn. Thank you thank you thank you!

[@ProfTaormina]

You are welcome, and thank you, your kind words mean so much. I teach mostly on-campus classes, and we've been closed since March 10, as our college is in the current epicenter. I'm happy that my videos are reaching some confused students out there and making a difference :-)

What if it doesn’t include the mean but the sample standard deviation ?

[@baiter5844]

JUSUS THIS WAS SO HELPFUL THANKM YOU

[@danielnelson6903]

Thank You So much God bless you

[@danc5644]

I'm sure this video would be helpful if I even knew wtf I was looking for. I don't know if I need a T or a Z interval. I have 2 sets of stats, 2 means.

[@rugvedkulkarni1593]

On TI-84 Plus CE it asks for standard deviation when calculating ZInterval using data. Does anyone know how to quickly enter the Standard deviation of the data set?

[@millenium2003]

My exam is multiple choice. So I'm good

[@samuelkintu7660]

Thank you!!!

[@elenasandalova4150]

OMG your life savior ! Thank you a lot!

[@oraliax4474]

What if instead of the mean, we have to find CI Interval using the median?

[@jessiemayfield6749]

What if you just get positive and sample size, no mean, no deviation. Then what?

[@chrischang6193]

Goated

[@mdonohue555]

thank you.

[@legolover9226]

Thank you!!!!!!

[@tonybalony4822]

1:35 absolutely helpful!

[@00ibraa]

Thank you! it was helpful.....

[@kindallcruz7434]

How do you put the data in?

[@killerkoegel]

thanks bruv

[@Mudmusk3]

SOOOOO HELPFUL THANK YOU!

[@struggle375]

how the fuck do iget the sample mean and calculate teh fucking confidence interval when given only 2 values........................................

[@nccassessment4069]

I'm sorry you are struggling. What two values are you being given and what do they represent? There are different ways to calculate a confidence interval based on the information your problem provides.
