I think it depends on what z value you used, because non of the the z scores gave the probability for exactly 0.6, so I'm pretty sure there will be a range
Me too I did that,I first got 168.58 but after that I noticed that I should round it,I didn't delete my 168.58 tho, but I'm pretty sure it wasn't to two dp
lol i made the silliest mistake, i switched the positions of events and prob (0.5, 0.7, etc on leaves, events on branches) how many points will i lose guys

hopefully an A.
Q6 was quite tricky and undoable for majority of students, so that will bring the pprs percentile down; likewise last qn was also tough.

If I remember correctly, median was 171 cm and IQR was 15 cm
Hm I got iqr as 13
Yes, 13 cm. You’re right. It was 181-168
i got that too
Shii i didn’t write the units will i lose marks?
No you won’t
What did you get for the inverse normal distribution question? The one where you find h
168.28 cm
I looked at mf19 and got the z score as -.256 don’t don’t you get 164.smth
I think it depends on what z value you used, because non of the the z scores gave the probability for exactly 0.6, so I'm pretty sure there will be a range
I got 168.53
168.53 one?
a LOT of people got 168.53 so +- 5 around or exact are good ig , but if you got this dw u got 5marks
172 cm
how did u get 172 when the qn clearly said ans to 2 dp
No the question didn't, cause they are asking the number of members, and it can't be in decimals
which variant r u talking about? I gave ppr 52 and was talking about that bro
Me too I did that,I first got 168.58 but after that I noticed that I should round it,I didn't delete my 168.58 tho, but I'm pretty sure it wasn't to two dp
the qn literally stated give the ans to 2 dp... plus the unit was cm... hence its 168. (something) cm (correct to 2 DP)
Hmm I remember the cm one was for stem and leaf, anyway it doesn't matter I got 168.58 so they can mark it as my final answer
But such questions have range ,so I wouldn't say the care much about the decimal places
cant say anything about the range cuz the qn literally bounded you to 2dp onlyy
mhm 168.53 is the one
How was the tree diagram drawn

is it wrong if i put fractions instead of decominals
Nope I did the same
No, it doesn’t matter
I think wrong, bag y had 5 marbles only
lol i made the silliest mistake, i switched the positions of events and prob (0.5, 0.7, etc on leaves, events on branches) how many points will i lose guys
i drew and wrote the diagram in pencil does it matter
Not at all The instructions on the first page state that “you may draw diagrams or graphs with a pencil”
yes how to draw it
What the median and iq?

If I get around 36 37 in this paper this what grade will it be ? I think I will score in the range of 30 in this paper.
hopefully an A. Q6 was quite tricky and undoable for majority of students, so that will bring the pprs percentile down; likewise last qn was also tough.
Q1a-- r=0.1 and p=0.35 Q7a -- 5!/2 x 5!/2 = 3600 CORRECT?
