you use z test if you're given the population standard deviation. she probably just calculated her sample standard deviation
Thank you. You are the greatest in the whole wide world.🙏🏼
This explanation is outstanding.
Why are you using T test if the standard deviation is given? You use t test when it’s not given.
standard deviation given is from the sample, not the population, thus a T test
thank you for showing this! my prof didn't know how to show me on my ti83 since he owns a ti84
Hey can someone help me understand why she used t-test when standard deviation was given? this is really confusing me. thanks.
How do you plug in alpha (level of significants) in to the TI that you are using?
This was so helpful. BTW I love the accent
Hey Vanessa. It's Aaron, Anna's sister. Thanks for the help again :) !
A t test is for a unknown standard deviation?
This was so much help to me! Gracias por todo!!!!!
That was so elegantly explained!
Why the t value given as this process is not equal to the t value by using inverseT distribution???
Hi what if I have a list, what if I have two lists and want to find the t test?
+Keisan Gittens Do a two-sample t-test instead. I had the same problem.
Hello Need help with the following: Determine the standardized test statistic, z, to test the claim about the population proportion p>0.015 given n=150 and Phat= 0.027 a=0.01Your input is greatly appreciated. Thanks!
What if the standard deviation and mean are unknown?? I'm so lost...
you're a lifesaver!
KEEP TEACHING PLEASE!!!!
thanks Nicholas. This is my new channel :) . Thanks for your message :)
omg you saved meeee thank youuu!
happy it helped you :) . VG
Can you please make a video using an example of finding the "z-score cut off" ?
i cant change the sign grater than to less than? on calculator?
Thanks much. I got it now. God's blessings.
Thank you so much for this video, well explained !
Null is not always "="
Makes sense, thank you!
Every time I try go down to x (mean) on the t test part an error screen pops up. Why is my ti 84 doing this?
Gracias💕
I feel like my cleaning lady is super smart!
lol, I am the author of the video and I thought this was hilarious. Go freedom of speech! VG .
Very helpful, thanks.
so helpful~~
THANK U 💯💯💯
you are confusing your z-test with your t-test! You have a SD so you can not say this is a t-test!
Very helpful
it should be right tail (cola) not right tale (cuento) .
thanks it worked great
What if my p value is larger than the alpha level?
+Vanessa Graulich alrighty makes sense. thank you so much I have huge project due soon and had no idea how to do this. big help.
Cardi B...... tighten me up on my B Stats...lol.... #MotorSport
i need to get the test statistic? this wasn't helpful if you can tuse the fucking calculator! im so mad!
thank you
Yay
