Homework Help: Statistics (Check Answer)

Posted by Jen on Monday, June 16, 2014 at 6:50pm.

Hi can someone check my answer. I'm not sure why the computer keeps marking it wrong.

**Suppose a random sample of size 50 is selected from a population with σ = 10. Find the value of the standard error of the mean in each of the following cases (use the finite population correction factor if appropriate).

Question: The population size is N = 500 (to 2 decimals).

My work:
1.4142 sqrt ( 499/450) = 1.49

I keep getting 1.49 but the computer is marking it wrong. I'm not sure what I am doing incorrectly. Thanks for the help.
