How did Statistics P63 go?

[Patterson]

What did you guys think of statistics 63? What do you think the grade thresholds will be? What questions did you find challenging or strange and do you think that there will be lots of scaling as you think this paper was much harder than previous years? (its been over 2 days so questions can be discussed)

i think is not that hard..but for the question 2,about the (xxx) square..i duno how to solve it...

 

[Mattman]

WHats your awnsers for the combinations and permutations part?

Also what graphs u pick for the 1st question
THe paper was a lot less simple than previous papers tbh.

 

[maggie wan]

i chose the stem and leaf graph for the first one and the histogram for the second one

 

[Mattman]

Oh same.
What ws your awnser for the standard deviation and mean for the normal distribution?

 

[Mattman]

I hope the gt will be about middle 30s

I didnt quite remember the answers but could you tell me perhaps I can remember ......~~~~~~

no1 is said stem and leaf, the histogram
no2 n=15, the X^2 thing is 150 something
no3 360 and 480 the last one i forgot
no4 the variance etc was in fractions i think..
no5 i remember the P(A|B) thing is 3/11 i think

I Really didnt quite remember but question 2 I got the same as you and no5 is the same

any1 remember their permutations/combinations awnsers?
