what ws the mean then ?

do u remember all ur ansers

53. something or around that.

53. something or around that.

ya so my mean ws right but then why wsnt summation x^2 comming right...stupid calculator !!!!, it gave me permutation of 3!x2!x4!x6! in 5180000s smthing too, nd that ws the only part i managed to do right ,,,,curse u buttons.....ny how, do u remember variance too ?

variance was 16.81 or something.

var was 16.8

ya variance is right too,,, i can't figure out what made me get summation wrng, oh well atleast i'll get the working marks

 

[A*(a*)]

how much marks will i lose if i forget to convert all permutations and combinations answers to 3 s.f?
And how much marks will i lose if I wrote correct mean and var formulae but used incorrect 'p' in 'np' to calculate k and n.

 

[A star]

4-6 marks if all else is correct

 

[qwerty123123]

For the first tree question u do all the ways you can choose 12 trees and add them all up right?

 

[A*(a*)]

4-6 marks if all else is correct

why?? Would he deduct the marks everytime? I heard He only penalises once for not converting to 3 s.f?

 

[A*(a*)]

my mean in the first ques was 15.5.
In the very last part of the last question. Would anyone be getting marks for correct tree dig,? single mark?

he will conduct once for sig and then each part accuracy mark is lost

no sorry bro

How many of you considered the trees of a particular type identical. For example for part ii i said that no. of arrangements was 3! because the arrangements of the trees within each block is not important after all the hibiscus trees are not different. they are identical. If cie really wanted us to think that trees of a particular species are different then they are out of their minds. They could have given a better example which wasn't so confusing.....

The question clearly mentioned different. Even from a biological point of view, there's significant variation even within a specie, so the trees could easily have been different.

i had barely enough time to think each question through . and u had time to think like that

 

[fishfish]

on a scale from 1 to 10, how stupid am i for making the stem leaf on graph paper? :'(

 

[fishfish]

plus how did the stem and leaf even look like? it was really confusing
