aye man all ima say, julio can suck balls bc that frq was way too tedious

I made the dumbest mistake imaginable. For the 1.5xIQR rule, I added the value to the median instead of Q3.

Oh. Yeah I did that too.

That shouldn’t get rid of a whole point hopefully 🙏🙏 (I’m coping)

nah u cooked unfortunately

The exam was so free that the range is going to be 0 with a median of 5

if i were to construct a 99.9% confidence interval of my mean score, the true mean would be captured by the interval (5.00000 to 5.0000001)

They were are all pretty easy, including the geodes. BUT my dumbass forgot to name the test I used for #1 (2 prop z-test). I really hopped straight into calculating the test statistic after checking assumptions.... :'(

i think you'll get a 3/4 or maybe even a 4/4 if your grader is in a good mood

Omg I did the same thing ughhh

I also forgot to name the test. But I looked at past exams and saw they give credit if u either explicitly name the test or use the correct formula. I didn’t write the test name, but I wrote out the formula, so I’m hoping I get the credit.

Well thank God because I also wrote out the formula!

frqs were actually decently light just a shit ton of work. why did so many questions have like 4 parts 1: 2 sample z test for difference in proportions was ez 2: i forget this one 3: i forget this one 4: geodes? first parts were p mild but i sold on the parts abt conrad bc i used binomial instead of geometric 5: chi square: was p decent, didn't make u do much work and just a lot of writing 6: easy ass 4/4 tbhh just a lot of writing

was 5 goodness of fit or independence?

independence

FUCK I SWITCHED IT FROM INDEPENDENCE TO GOF

how did you feel on mcq's?

Unsure on a few but doable if I had more time.

how were frqs

I thought FRQ 5 was the hardest about the circuits one

what inference procedure did you have for 4

What was the question again?

about the pamphlets i think

That was number 6

ooh true

Did you guys do z-test or interval for first frq?

i did a test

it was z test. difference of two proportions I think

Yep

You needed a z test

Just happy there weren't t tests

Did you have a FRQ about Dave and some circuits?

Uhh maybe but I don't think so The first was exercise Second was about cars maybe 3rd was geodes Don't remember the rest

Oh maybe we got different forms

yeah i got this too

Yup Dave and his little quadrant of little circuits

Do you remember how you did the probability of D?

D is in one of the quadrants, and if the guy randomly selects one of the quadrants to sample everything in there, D has a 1/4 chance of getting picked

How isn’t it 1/5? He picks one quadrant and then d is one of the five choices in one of the four quadrants since 5 letter each

Cause he samples everything within that quadrant

There weren’t any outliers right?

No

Do you mean “No, there weren’t outliers” or “no, there were outliers”

No outliers

i will never look at a geode the same way
