Question

Check my answer

Answer 1

Sorry I dont know this one probably @phi can help...

Answer 2

@phi im positive #3 is right , but not so sure on the others

Answer 3

I'm thinking Q2 is D some outcomes are systematically favored

Answer 4

I guess that could be true,but it a if / or type thing

Answer 5

Q1 *might* be the last choice, because none of them are using chance to select their samples

Answer 6

give me a second please, to goole some things and I'll give a second answer if i have one

Answer 7

though the last example of the detective asking the questions is a different problem.
I think your answer for Q1 is the best.

Answer 8

Yes I tihnk my answer for number #1 is the best for whats given to us

Answer 9

But Q3 has me puzzled. if you want a random sample of say 100 out of a million
you don't have all million respond to the survey, do you ?

Answer 10

For number #2 I am going to change my answer to D
think thats best

Answer 11

what do you think for Q2

Answer 12

I thought D was best for Q2

Answer 13

oh ok good

Answer 14

For Q3 I can rule out A, B, D
but I don't like C (or don't understand it)
so by process of elimination I'm thinking E
but that is not a very clear.

Answer 15

hold on let me show you something for #3

Answer 17

oh, that definition is choice E in Q3

Answer 18

A simple random sample of size n is selected in such a way that every possible sample of the same size n has the same chance of being chosen.

Answer 19

oh you think choice E

Answer 20

yes, and if we boil that down,
every possible sample of the same size n to "sample of size n"
has the same chance of being chosen.

Answer 21

ok so i really dont know now, I guess I should trust what you say but for Q3 im really confused

Answer 22

hmm, interesting i see. so its the same size to the same thing

Answer 23

The definition you posted says
every sample of size n has an equal chance of being selected.

choice E says
all samples of size n have the same chance of being selected

those sound close enough for me.

plus, as I posted earlier, choice C, each member has a chance to respond means something different from choice E.

Answer 24

oh im stupid....... i didnt re-read the answer choice E to see what your talking about
I'm sorry but yes, I agree!

Answer 25

i am now try to reason why i chose C to begin with

Answer 26

You have a decent shot of getting these 3 correct. (but no guarantees!)

Answer 27

Yes, and with your help I must thank you so.... Hey
