This was the only video that actually showed me how to calculate the p-value. Thank you!!!

[@TheMelissamtz]

Same here. I spent so much time looking.

[@mikemccookie480]

Thank you! I've been trying this for two hours and it finally clicked and I heard the bell in my head!

[@Kari-0503]

Thank you for your video you taught me how to calculate the 1-proportion z Test. I have been struggling for 1 hour on only 1 problem on my review. I couldn't figure it out by hand and i have the calculator for it, i wanted to learn how to solve these Test Stats by hand and with computing it in the Ti-84 calculator. I thought its best to learn both ways just in case if one way doesn't work out I always have another way to find the correct answer just in case if I were to mess up one way over the other. I could not figure it out by hand for the life of me so I decided it's time for me to learn how to solve with the Ti-84 since I can't seem to get this 1 right. You showed me how to compute the numbers I had and it was the right answer on my calculator but on my paper I had it wrong. My Stats class is online now and I have to teach myself everything and it's not easy I am spending hours and i need to hurry up to cover every chapter on my test , thanks to the Corona Virus i have to learn this way. But if I don't pass this stats class i don't pass the semester, this is my last credit to go on to a 2 year bachelor program.This video is going to help me for my test thank you sooooo much! God bless you , you saved me!

[@virginiavelascocastellanos344]

Thank you! took me more than 24 hours to understand that I needed 1 propztest to calculate this!

[@nuevoriche1668]

[@robertomorales8751]

amen brother

[@KurlyKymme]

Praise the Lord for this video! I hate that Stats Lab says use technology to find your answer, but they don't tell you how to use technology! Thank you!

[@vanessachen2330]

Very clear explanation and precise instruction, thank you very much for providing the help video.

[@SheIsHisTV]

I wish I could give her an award.

[@fml2135]

I took hours trying to figure this out, so thanks for the video! so easy thanks!

[@natgonzalez9896]

Amazing. Straight to the point, informative and extremely helpful

[@probsnooneyouknowtbh3712]

The TI 84 plus CE came out in 2015. Why has hardly anyone made videos on how to use it? It's completely different!

[@ArthurHall]

The way my problem is set up, I cannot find x.

[@DrAwesome9]

Thank you very much! we are on our last chapter and i needed this greatly!

[@ruth..]

Dang, where was this video when I was looking on YT for help during the finals 😕

[@Adam-gp3ij]

Thank you so much that was really helpful

[@Jeramiahstool]

my questions arent yes no, i have questions given with mean and SD results, i dont know how i am supposed to find x when i am not given a percentage of a certain response of the sample size

[@repressedtears8568]

thank u

[@shelbypatton7602]

okay but how would i manually type this on my calculator bc my answer comes out different when i type it myself vs when i use the built in TEST feature

[@shahzaibraza5243]

Thanks for the explanation

[@jordanoquinn-campbell7613]

THANK YOU

[@Diomezzadra]

THANK YOU!!

[@jasemalkhaili5235]

amazing video thanks for helping out

[@frankq5637]

thank you very much !

[@ifutureman]

Where did the "5% significance level" come into play here? I don't see it anywhere in the equation, or being input in to the calculator

[@OpenIntroOrg]

The significance level is compared to the p-value (0.186) at about 3:50 in the video. The Greek letter "alpha" is shorthand for the significance level, so we're checking whether the p-value is bigger or smaller than than alpha. Because the p-value (0.186) is bigger than alpha (0.05), we do not reject H0.

[@plane12341]

Very helpful. Thank you!

[@VioletBloodbath]

Thank you for this! The last few I found made 0 sense

[@ellieiiams9558]

The problem I’m trying to solve is %’s of items in a package… not a yes or no question. Help?

[@OpenIntroOrg]

Are the individual observations percentages? If that is the case, then if the individual observations are being averaged, it would be appropriate to use a 1-sample mean method.
If that is the case, then below is a video that may be helpful:

The video after that one in the playlist covers confidence intervals.
