Stats: Hypothesis Testing using P-Value Method (Example) 

If P value is HIGH > the null must FLY If P value is LOW < the null must GO Amazing way to remember this.Thanks.

best video on the web to figure this type of statistical calculation out, hands down. Thank

You are significantly better at explaining statistics than "crazy hat dude" on RU-vid. Thank you!!!

THANK YOU SO MUCH! One of the very few youtube videos I could find that actually showed how to find the p value using the calculator!

You have the perfect traits for a great teacher. Very organized, thorough, simple. Can't thank you enough

I really wanted to thank you for your videos! After watching dozens of videos on p value i finally got it!! Thank you so much!

Watched 6 vids on Null hypothesis. Only this one made it crystal clear with a good example. Thanks a ton!!

One of the best explanation on u RU-vid

Great Video. Infact the best I found on RU-vid. Just clear that thing "null must fly away", it seems as if u are going to reject it....

@poysermath excellent presentation, sir; you have constructed a clear, methodical and thorough calculation of the p-value method for hypothesis testing. Best on the web that I have seen. Thank you so much!

Well done, I feel much more confident in this. Should do a video about the differences of sample sizes and how it effects the distribution as well as the ways of finding sigma. Thanks.

This guy is an awesome teacher

oh my God i finally understood what does p-value mean! THANK YOU so much!)))

Yiu just saved my whole semester..thank you

Thanks for uploading! Clear and concise explanation. This really saved my ass!

you deserve an award!!

Thankyou!!!! This is really good

Better than Khan Academy and lectures combined! LOL xxx

If the video is > that the rest on RU-vid, the LIKE must fly!

awesome explantion

Thank you so very much, Sir!

Thank you Sir, all your videos are helpful.

when you say null must fly it's confusing cause it's sounds like "null must fly away" i thought we gonna reject it. I think you need much clear slogan for it imo.

How can I find down this p value without the calculator? Thanks

great video. I learned a lot. Thank you very much.

Thanks for saving my mark! xD

Amazing!!!!

Thanks for sharing!!! :)

best video

Great

Thank you so much :)

thank you!!

We reduce the probability of type 1 error using p value method? because with p value based rejection ensures it is far less than even the given significance level, thus avoiding type 1 error? Please verify my understanding. I understand in this example p-value is supporting the belief or Null? Thanks

What if x-bar isn't given in the problem?

thank you sir! you saved my butt!

Omg thanks.

excellent! thanks! helps a lot! Let fly the NULL !!

What if my test statistics computed using chi square and it is left tail test. Do we say if P

Do you double or half p value for a two tail test

but with this problem you can argue and say the claim is from the battery producers that the mean battery life is 30 hours

amazing.
