Don't know how I ended up back here after like 5 years. But, I remember going from 10/75 in a mock exam to 100% across all past papers and 100% in my actual exam after watching all this guys videos for literally just 1 week. Graci.
I’m going to do hypothesis testing with 2.5% significance level, H0: p=0.05, testing for H1: p>0.05. To see if this is significant, to see i can reject my null hypothesis to see if the probability of going from 10 to 100% across all exams is more than 5%. Props to @TLMaths for teaching me this.

genuinely I've stopped enjoying maths at school, but these videos make me feel confident in it again. thank you so much 👍
how's it going now?
I was looking for pple like u
My maths teachers took a whole week to teach us this concept. You taught me in 4 mins. Thank you really helpful!
💯
A really clear and helpful explanation, many thanks.
Great vid!😍
My teacher didnt even explain these terms, had to come here to do my homework
Just brilliant!
Why is it that when working out venn diagrams you cannot use P(A) x p(B) to find P(AnB) but when in normal probability this rule applies?
The rule applies if and only if A and B are independent. If they are not independent then P(AnB) does not equal P(A)xP(B)
@@TLMaths Ok i understand, Thanks
thanks for the help
Are you suppose to mention that P(A or B)=P(A) + P(B) for mutually exclusive events?
That is a consequence of being mutually exclusive and you can use that to show that A and B are mutually exclusive.
thank you!
What would a Venn diagram with independent events look like? Thanks.
The Venn diagram of independent events could look much the same as one of dependent events.
