Question

Who wants president Obama Impeached and who does not Democrat Republicans
Wants him as president 6 2
Does not want him as president 4 8
3. Choose a row and column and compare P(A | B) with P(B | A). Explain what each probability means in the context of the situation and data you collected.
4. Compare P(A∩B) with P(A∪B), and explain what each probability means in the context of the situation and data you collected.

Answer 1

I could use some help with what to do

Answer 2

Democrat Republicans
Wants him as president 6 2
Does not want him as president 4 8

Answer 5

I don't want answers just which rows it is asking me to compare and how to answer these questions

Answer 6

spose we want to find P(want|dem), prob of wanting given that its a dem

we know the total of dem is 6+4

and there are 6 that want.

P(want|dem) = 6/(6+4)

Answer 7

not too sure what the question is asking, interpretation is not a strong suit of mine

Answer 8

It wants me to compare P(A l B) with P(B l A) But i dont understand which row is which.

Answer 9

I am guessing it is like this

A B
A
B

Answer 10

you might have to define them as such. that would be suitable to me

Answer 11

A|B = (AnB)/B

Answer 12

so you might need to subscript them

Answer 13

if P(A|B) means P(want | dem ) then P(B|A) means P( dem | want)

Answer 14

B1 B2
A1

A2

Answer 15

A= democrats B=Republicans
Like A = who does want him
B= who does not want him

Atleast i think

Answer 16

its best not to define t seperate things by the same name ... works well with children, but not really suited for much alse; cats maybe

Answer 17

*two seperate things

Answer 18

as phi points out, just define one row as A, and one column as B to co the comparison with

Answer 19

ok so what do I do with that ?

Answer 20

okay but what about the second I understand what you mean by the first now

Answer 21

B:
Democrat Republicans
A: Wants 6 2
Not want 4 8

Answer 22

Would you consider this a bad example for independent probablity

Answer 23

evaluate P(A|B) and compare it with P(B|A), why does the probability change? what is the notation telling us about the information? etc...

Answer 24

Sorry I know this may be getting annoying but so should I just do the percent probability or something to compare them or just say that the democrats want him to be the president more than they dont want him to be?

Answer 25

id focus less on trying to read the minds of the participants and just focus on how to interpret the given data in a statistical fashion.

Answer 26

so like 60% of the democrats I interviewed would rather have him as president

Answer 27

the probability of A, given that we have chosen B to study, is the amount of A that is IN B - the set defined as AnB.
