For part C, why did you do 1/3 multiplied by the probability of the distance being greater than 4.3, didn’t those who achieve a distance of atleast d metres also receive a medal?
@@MrHassaansMathsChannel It said that those who achieve a distance greater than 4.3 receive "a medal" it did not say a gold medal though, and those who achieved a distance of atleast d metres also received "a medal" thats why Im confused
hello sir i wanted to ask whats the best way of studying statistics the exam is on thursday adn i still tend to face difficulties in solving past papers
Pick a topic that you are having issues with and go to the playlist and watch some videos on that topic -- use the index as this video shows how ua-cam.com/video/7gb-yPzWAUY/v-deo.html
So in question (b) why didnt you divide the probability given by 80% I mean isn't 80% of those who achieved certificates using the 80% alone is like using the 80% of all the students
i really do not understand what you are trying to say... we found the value of z such that 80% of the whole sample had a jump that was longer than that value
@@MrHassaansMathsChannel what am trying to say is he said in the question 80% of students WHO ACHIEVED .... so shouldn't we divide 80% by the probability of students who achieved.... because using the 80% alone is like the 80% of all students not just students who achieved medals like in previous question where they used to say for example GIVEN THAT SHE QUALIFIES FOR THE FINAL so we divide the probability they are asking for by the probability for qualification for the final because if we didn't do that it's like we are just finding the probability she qualifies
The question is saying that 80% of all the students get medals - those who got more than d. Find d... I think you have misunderstood what the question is asking
I don't know why I thought this but he sounds like Thor lol
Nah
WOOOOW VERY FANATASTIC VIDEOO!!!

We want those who receive GOLD medals.... not just any medals

mr hassan thank you for everything man❤️❤️❤️
Why didn't you multiple 1/3 by 0.80 in part c
I love you
for question C, why did u use 4.3 and not 3.04?
How do you know when to standardise it and when not to?
THANKS A LOT SIR

me too bro 😭😭😭😭good luck! probably won't see you but at least we'll suffer together.
@@toodles8397 good luck to u two. I’m also doing it tomorrow :) remember not to panic as that it is the most crucial thing
what is the difference between wst11 and wst01 ??
st01 is the old specificatiom, st11 is the new specification (2018)

Part c is now limiting the sample space to to those who got medals only
@@MrHassaansMathsChannel ok ya I got it now thanks 😊
