Thank you for making this easier to understand!
Thanks a lot, I was having a lot of trouble understanding what I am suppose to do though. Question though, what do you do if you don't have the middle point for the z scores, and your professor does not allow you to use to calculator to figure it out?
You didn't show how to use the calculator
How do you come, on the TI-84, to .3355? On two different TI-84s, a Plus and a Plus CE-T I come any time on .1645
10 years later you've helped me comprehend this concept so easily. I truly appreciate it and hope you're doing well.
clutch
Thank you very much
Thank you for explaining the calculator formula as well. Helped me so very much.
what about technology for two-tailed
thank you!
I hate probably 🧍🏿♀️
Thank you 🥺🥺🥺
Me too holy molly

O star,you are a star...danko
Thank you so much. You help me for my task huhu 😭
U really need almost 6 minutes to convert a line plot into a scatter plot?
Thank you so much sir
entereseting
THANK YOU! The whole "use technology" thing always gets me! There's never any further explanation about it!
Yessss like wth
Muchas gracias por tu vídeo, no sabía cómo sacarla en mi programa y ya con tu ayuda ya me salió, gracias brou:v <3 kisses4u
Thanks a bunch
these are great ASMR videos
Omg! Thank you! This helped me SM!
Thank you so much for your help.
HERO !
So helpful! Thank you
THANK YOU! I have a stats test tomorrow and this really helped me understand how to find a z-score when given alpha. You're a life saver!
z table makes NO SENSE
I liked your video but your mic caused ringing in my headset at times.
You still don't explain it well. How do I know to move to the second asterix. There is no asterix on a paper z score table
Flawless man
Not helpful
i still dont understand
where did you get 8.5 from?
Thank you!
this is what i was searching for. thanks fellas
thanks
Thank you, still amazingly helpful 6 years later
Thanks sooooooo much!!! Love your explanation!!!
Is that me talking?
thank you
Can this same Z score be calculated using a formula in excel?
Thank you, this is the best video I have seem so far. To the point on what's important regarding solving the problems with keys points of what to look for in solving the problem. Thanks alot.
I do not understand! I am an online student and everytime I give an answer on this it's wrong
Thank you very much. You helped me understand the P value. I wish our instructor would teach the same as you do; plus go over the use of TI-83Plus calculator! Awesome job
Life saver! Thank you
You didn't show how to get the critical values which was a part of the question.
i love you
