Question

Its a statistic question:

If the standard error is 18 and the N is 36, what is the population standard deviation?

Answer 1

Welcome to OpenStudy!

Answer 2

....but I can't help you, sorry idk :(

Answer 3

\(\dfrac{PopulationStandardDeviation}{\sqrt{SampleSize}} = StandardError\)

Answer 4

@tkhunny Is the answer 6?

Answer 5

That seems unlikely.

\(\dfrac{TheAnswer}{\sqrt{36}} = 18\)

Solve for The Answer.

Answer 6

@tkhunny Can you work it out with me step by step

Answer 7

Yes. You can, too. Please demonstrate some knowledge of algebra. Go!

Answer 8

\[\sqrt{36}= 6\]

Answer 9

thats all i know. I don't know what to do next

Answer 10

Okay, now we have \(\dfrac{TheAnswer}{6} = 18\)

Keep going.

Answer 11

Will the answer be 3?

Answer 12

okay is the answer either 3 or 108?

Answer 13

You tell me. How do you get that 6 away from The Answer? Did you Multiply or Divide?

Answer 14

What i did was that i divide 18/6 and got 3

Answer 15

Why did you do that? Why do you think that is the right thing to do. You are trying to get The Answer by itself. Your trouble is that it is divided by 6. How do you UNdivide it by 6? Divide it by 6 again? That doesn't help. How do you get The Answer ALONE. No one cares about the 18. Just answer the question.

Given (TheAnswer)/6 what does it take to get just (TheAnswer)?

Answer 16

I don't know how to solve this. I kindly ask for help. You seem angry and impatient

Answer 17

I'm terrible with statistics. I simply ask for someone that will work with me step by step and guide me to get the answer

Answer 18

Neither. You're just not answering the important question that will teach you how to do it. I cannot help you answer this question. No need to evaluate me. Just answer the question.

Given (TheAnswer)/6 what does it take to get just (TheAnswer)?

Answer 19

Dragoon can you help me?

Answer 20

@patty27

If you cannot solve \(\dfrac{x}{3} = 5\) for x, then you do not have sufficient prerequisites to be in this statistics class. Please rethink your response. Can you solve this sample equation?

Answer 21

I am being honest and direct. These are often mistake for unhelpful and rude. Try to get past that and just answer my questions.

Answer 22

Hey maybe I can help. If you are dividing a number by 6, and you get 18, what can you do with 6 and 18 to get the number you need? As tk said, undivide. And the opposite of dividing is what?

Answer 23

multiply @horsegirl27

Answer 24

Yes, multiply.

\(\dfrac{TheAnswer}{6}\cdot 6 = TheAnswer\)

On the other side, \(18\cdot 6 = 108\).

No need to guess if it is multiplication or division. Prove it!
