Exam 1.....Forget about it.

[superstar1]

Exam 1 is done and dusted. I suggest we forget about it and concentrate on exam 2. (still im not sure about q3 core)

I'm trying to learn from my mistakes in this exam so I don't do it again on exam 2.

[superstar1]

wow. uve got a point. but i thought they dont repeat he same concepts.

[Gobon]

Yeah, I guess that's true. But you can still make the same kind of mistakes though.

[superstar1]

yeh tru. like in q9 in trig i had a similar question in my SAc extended response and i got it wrong. never leasrnt from my mistake.

[MrIraq]

yeah question 3 in core,, that was bull shit in all thoes 49 trials walla i never saw anything like that

i took a guess said, once they tought us that standard dev ~ Range/4  ..... but that gave me 3.4,,,  and then i was like hmm.. 3 . and it was 2?!!?!! what the hell

Bell curve Sx is equivilent (or close to) Range/8, as it equally divides the data into 8 sections as does the bell curve rule

My bro worked out another method. Using the 99.7% rule, work from the outside in towards the middle. Your standard deviation will be 2.

just look at the curve, you knew Q1 and Q3, then you knew it had to be a bit further out, another 9% to reach the 68% rule so add a little on to the 1.5 of Q3 it had to be 2

Same as what I did

Ahah nice use of the box plot, yes you are right that could work too

I'm guessing exam 2 will have all the stuff that exam one didn't? But I felt like that it covered most of it. The only thing I found that wasn't covered was annuitites and unit cost depreciation in the business. Happy to be proven wrong since I don't have my bounded reference on me.
