i didnt realise 33d was linked with the other fml
DID YOU DO WELL?? why am i the only one who did shit everyones getting 90s wtffdkhlkhdflhdfkmate each time someone discusses my mark starts to deteriorate even more
bro i got 0.045 dont even aski got 743 for the babies
mate the only way to know is when i see my markDID YOU DO WELL?? why am i the only one who did shit everyones getting 90s wtffdkhlkhdflhdfk
oh wtf. Didn't even realisei didnt realise 33d was linked with the other fml
I WAS GONNA DO THAT BUT I GOT LIKE 0.2I think its wrong, they gave u the mean and SD so it has to be something to do with z-scores which the answer didn't include. not to mention the z score is exactly 2, so probs with empirical rule as well. i did it as a conditional probability
ahh, that makes sense. So probably probability of picking someone with 130 iq GIVEN that they finish the puzzle under two hours. Then i'll probably get 1 mark since i calculated the z value.I think its wrong, they gave u the mean and SD so it has to be something to do with z-scores which the answer didn't include. not to mention the z score is exactly 2, so probs with empirical rule as well. i did it as a conditional probability
ok at least ill get 1 mark alsoahh, that makes sense. So probably probability of picking someone with 130 iq GIVEN that they finish the puzzle under two hours. Then i'll probably get 1 mark since i calculated the z value.
yup i think its conditional probability as well... the solutions look somewhat right, but i am unsure.ahh, that makes sense. So probably probability of picking someone with 130 iq GIVEN that they finish the puzzle under two hours. Then i'll probably get 1 mark since i calculated the z value.
that's GOOD. 1 mark can make the difference between band 6 and 5ok at least ill get 1 mark also
i got like 10k or somethingwait im pretty sure Q25 has worked it out incorrectly
they said 8(1000) x 8.2132, but i swear it should just be 1000x8.2132
yeah it cant be anything higher than 20000i got like 10k or something
yeah, you're right.i got like 10k or something
The answer given for q33(d) is incorrect, it is a conditional probability problem as the question asks for P(IQ > 130 given can solve the problem in under 2 h)Sir, can you check question 33? is that right? Aren't they independent events? So shouldn't it just be calculating the z score of z=(130-100)/(15)?
could you check q25?The answer given for q33(d) is incorrect, it is a conditional probability problem as the question asks for P(IQ > 130 given can solve the problem in under 2 h)
Thanks, i got it nowThe answer given for q33(d) is incorrect, it is a conditional probability problem as the question asks for P(IQ > 130 given can solve the problem in under 2 h)
yep, thisyeah it cant be anything higher than 20000
it should be 8419.81
1000x8.2132 = XYZ
XYZ(1.0125)^2 = 8419.813313
she has only invested 8000, i doubt she could accrue another 60000 lmao
