Question

*Will fan and Medal*
An experiment is set up to study the weights of 35 mice after they are injected with a drug. The population mean is 23.50 grams with a standard deviation of 3.40 grams.
The standard error of the sample mean is BLANK
. (Round off your answer to the nearest hundredth.)
What is the blank?

Answer 1

Looks like the standard error of the sample mean is \(\large SE = \frac{\sigma}{\sqrt{n}}\)

So here we have \(\large SE = \frac{3.40}{\sqrt{35}}\)

Can someone else confirm though?

Answer 2

Thanks a lot, Is there a more simplified version of the answer or is that as far as I can simplify it?

Answer 3

like is that the correct answer form?

Answer 4

Well no they want the answer rounded to the nearest hundredth!

So we actually must evaluate that

\[\large SE = 0.57\]

Answer 5

Yeah I got that in my calculator just double checking thanks a lot.

Answer 6

Of course! :)
