finally at the end of stats, wow its been a long couple of days but i got there. The addition of conditional probability with normal distribution is very interesting and thank you for this playlist
Hi sir, have you got any experience with the single statistics (not combined with pure and mechanics) a level? I think Edexcel released it not too long ago and the exam code is 9ST0. Not many resources online so just wondering if you will ever release videos on it? (I’m aware some of the content is just FS1 and FS2 but there is so much more).
I don't have experience with this - but something that I might look into, I wonder how popular this qualification is? Interesting, something for me to think about!
I know the question before even looking at it... not something I will do this year as I've got too many requests, but something I will add to my long to-do list... I'm sorry!
Because we are saying the probability in the numerator needs to be that it is greater than 127 AND greater than 133, this is combined into a single expression of greater than 133, as this is the range that satisfies both. If you did your one, you would be finding the probability that it lasts less than 6 hours, given that it has already lasted for 127 hours. Hope that helps!
@@BicenMaths thanks for ur reply. I have 1 more question to that, if we said the probability is greater than or equal to 127 but less than or equal to 133 would that be saying it lasts 6 hours. I know we can't say equal as this is normal distribution but if we just forgot that it was normal
Hi, for normal distribution questions in stats and clt questions for further stats, there is always an M1 mark for standardising using the z dist.. If I use the inv. normal function of my calculator will I still get this mark
I actually don’t advise my students to standardise - I always advise to use the inverse normal function. This will still get the mark as the method is perfectly valid!
Can't believe I have reached the end of learning stats content , ty for all the vids
You’re welcome!
5:00 I want a phone that lasts 100h on a charge 😂

You're welcome! Well done!
Ah fellow haikyu fan!! Bicen has single handedly saved my maths a level for sure
thank you im finally done !!
Well done! 👏🏼
genuinely hope you have a happy successful comfortable life 🙏

sir can u make a video going through question 24 on the mixed exercise on chapter 3 please?
I know the question before even looking at it... not something I will do this year as I've got too many requests, but something I will add to my long to-do list... I'm sorry!
@@BicenMaths its fine sir i understand you are very busy but thanks for all your stats videos they have tremendously helped me
You’re welcome! Thanks for understanding!
thanks a lot , the videos were really helpful and scored my best in stats a level paper 🙏
That's great! Congrats!
I'm trying to understand for question 2 why would it not be the probability that is 127
Because we are saying the probability in the numerator needs to be that it is greater than 127 AND greater than 133, this is combined into a single expression of greater than 133, as this is the range that satisfies both. If you did your one, you would be finding the probability that it lasts less than 6 hours, given that it has already lasted for 127 hours. Hope that helps!

Yes that’s correct! And you’re right that it doesn’t matter if it is equal to or not with normal!
