and for cumlative graph it was a total of 200

to get median 200/2 = 100 using the graph 100 = 3.5
q1 was 50
q3 was 150
iqr = 100

using grpah 100 =3.5
so u should of got the same median and iqr r the same

Wrong sir, you are calculating for q1 the actual value of the 50th data set and same for q3 so the iqr was like 0.7 or something like that.

This is hard to explain so bear with me. i calculated the probability of getting the combination of part 1 3 times and the 4th probability is not 2 women and man not getting the prizes. Then i think there are 4 ways of arranging it and added this to the proability of the prizes being awarded 4 times. I did this because i think it asked for the probability of more or equal to 3 and it said there were 4 events

Yeah I understood soon after you stated your answer, any ideas how much that question was worth, 3 marks?

what did people get for the very last probability question? did u get a standard form answer?

Yes it was 5.6425*10^-3

Yikes :P, nvm probably the only one I messed up in then. Although the asking for a reason questions I hate so very much what did you write for should the outlier be counted for the baby one.

yes sorry there was 25 numbers ... so it would be the 19th value for q3 and the 7th number for q1 anyone got the same ?

5.62. I'm really hoping i put a 6 instead of an 8 :frown:

aah yes. I think i might have waffled a bit with that

so if i am wrong in the cumulative iqr part i still get a mark or two for calculating q1 and q3 and writing the formula for iqr ?

i put to count it and waffled a bit, not really sure what i should have put :K:

i think the only place i lost marks is for putting 5.82 instead of 5.62x10^-3 and calculating the first iqr where i didn't add 1 to 25. If so, I'm hoping thats less than 5 marks in total?

Couldn't say mate, sometimes they give it sometimes they dont. In this case probably not.
