Answer 1

do you know how the CIs work?

Answer 2

yes but I still have trouble with these problems.

Answer 3

Well, are you able to find the margin of error?

Answer 4

I need help with how to set up the formula.

Answer 5

Did they give you a formula they want you to use or a list of them?

Answer 6

no.

Answer 7

Hmm... the way I have done it requires the number of samples to find the critical value. =/

The CI is the sample plus or minus the margin of error.

Answer 8

Is there just a formula used to find the confidence interval?

Answer 9

Yes, but you are missing information for it... so there must be some other formula they want you to use.

Answer 10

What is missing from this question?

Answer 11

Like I said, the number of samples.

But they may have some way around that which I do not remember. It has been a while since I had my statistics class.

Answer 12

No. I am sure there is something I am just not aware of. Without having done stats recently I am just not sure what it is.

Answer 13

ok. thanks for trying though.
