Do you think this exam was harder than last years?

Yes, that's my impression, though it strikes me more as challenging than unreasonable.

 

[stressedadfff]

so would we get scaled up orrrr

girl how did u go

girl how did u go

horrid - couldnt be worse! wbuuu

The probability you are looking for is P(Z>0.4). The table only gives you P(0 < Z < 0.4), so you're missing half the entire normal curve. This means you need to do a bit of manipulation first
P(Z > 0.4) = 1 - P(Z < 0.4) = 1 - [0.5 + P(0<Z<0.4)] ~ 0.5 - 0.1554 = 0.3446

The answer in the attachment is wrong. You cannot have more than half of the babies being above the average for a normal distribution.

What do you think about this year's exam? (if you've gone through it)

equally horrible woooo

Ahh, ok. At least there's scaling to compensate for that

 

[CM_Tutor]

The answer posted for Q23 is wrong, too. The derivative of is (as the solutions state) only if . The derivative is actually .

 

[stupidpersonlol]

wait but ive just checked the scaling report and in the past years its around like 77-80 minimum to get b6 so would that mean this year its like 65?

 

[stupidpersonlol]

imagine if we're like the only ppl who found it hard and the james ruse kids are quietly enjoying it

Unlikely... The highest scaling before was the 2013 paper in which the band 6 cutoff was 75.

omg... i just checked the solutions i did not scrape a band 3 ... do i cry or kms orrrrr???

 

[DarkOperator618]

i aint even gonna look cus i don't wanna stress

 

[stressedadfff]

i wish i didnt see the solutions im actually clinically depressed for a weak i cried enuf today - im gonna get disowned by myself

;((((( did u get less than 50

 

[stupidpersonlol]

true i cant concentrate anymore

i wish i didnt see the solutions im actually clinically depressed for a weak i cried enuf today - im gonna get disowned by myself
