[hacksign000]

so the confidence interval is basically "how sure" we are about our estimation about the population :)?

Do you always divide your standard deviation with the square root of your sample? Thanks for a great upload!

[aghasemi4u]

When you want to find out the standard deviation of the distribution of sample means,

You divide the standard deviation of the population with square-root of sample size.

The other name for standard deviation of the distribution of sample means is "standard error of the mean" SEM
