when finding CDFs do we need to write it in 3 part piecewise form or can we just leave it as is? thx

This is what i was thinking, Im going to write it in both ways just incase

Wait what 3 part thing? What?

yeah I don’t really understand either, don’t you just have to find if the integral of the PDF is equal to 1 or something?

they're referencing whether a cdf should be written with three parts, as there's a section for when the cdf is 0, and then the next section is the result that you get from integrating the pdf, and the third section is 1 (after all datapoints have been taken care of within the pdf), and yeah it's from integrating the pdf but it's best to include the '0' and '1' part for completion as you demonstrate understanding that the domain of cdf exists outside of the pdf

best of luck everyone

what the fuck was that test

 

[abstractaviator]

what the fuck was that test

yeah I don’t know what the actual fuck that thing was

 

[dannyo1]

test

That was what we call NESA taking great pleasure in collectively bending the class of 2021 over and truly fucking us

 

[specificagent1]

that was so fucked wtf what was the expected value question???/

 

[hellohowslife]

that paper was made by the devil

 

[abstractaviator]

I think I got ~30% lmao, I almost asked the nesa lady if they accidentally gave us the extension 2 exam instead of the advanced one

 

[abstractaviator]

yea that question was funky

 

[hiiitsme]

I smashed it letsss goooo

 

[dannyo1]

Well the bright side (I guess) is that alignment will probably be pretty generous this year if everyone in the state thought that paper was the spawn of satan, which it appears they do lol.

 

[hiiitsme]

What did y’all get for q10?

 

[dannyo1]

What did y’all get for q10?

was that the composite function one?

 

[sandybay]

what was that last Q about. Totally f up

 

[hiiitsme]

was that the composite function one?

the one where it was 1/2pi 1/a and m

I can’t decide whether the exam was way harder than last years or whether I can’t math in exam conditions.
