Answer 7

I am so sorry, I have no idea :(

Answer 8

kk

Answer 9

we have 2 subsets of data, so the mean of the resultant set, is given by the sum of those means of the 2 subsets

Answer 10

so 2.2?

Answer 11

cause i added the mad and the decimal is 2.2

Answer 12

4.3+4.9=...?

Answer 13

similarly for the absolute deviation, namely:
1+1.2=...?

Answer 14

9.2, is that it?

Answer 15

wow

Answer 16

ok!

Answer 17

9.2 +2.2 =11.4

Answer 18

cause u add both, do u not?

Answer 19

no, those are two distinct values, namely
mean = 4.3+4.9=...?
and
absolute deviation = 1 + 1.2 =...?

Answer 20

9.2 and 2.2

Answer 21

that's right!

Answer 22

and add them together which equals 11.4, right

Answer 23

no, you have not add together, since those values have different meanings

Answer 24

okay, so it is 9.2 and 2.2, what is next?

Answer 25

after that i mean

Answer 26

sorry what is the meaning of MAD?

Answer 27

9.2 and 2.2

Answer 28

then you have to compute this ratio:
9.2/2.2=...?

Answer 29

4.181818181818......

Answer 30

so basiclly 4.18

Answer 31

better is 4.2

Answer 32

okay, is that it, really

Answer 33

wow, i should have known,

Answer 34

no is it not 4.1 though

Answer 35

it is not higher than 5, so it must be 4.1, right?

Answer 36

we have to round off it, and I think that the best value should be 4.2

Answer 37

umm... okay
