# Thread: Statistics - samples. Test tomorrow?

1. ## Statistics - samples. Test tomorrow?

Please help me understand what this means, how I am supposed to do this.

From the x row, select without replacement and list a samples of a size n=2

X 1 2 3 4
P(x) 1/4 1/4 1/4 1/4

Calculate $\bar{x}$ for each sample and list the unique $\bar{x}$ values. Construct a sampling distribution for $\bar{x}$. For the sampling distribution find $\mu$ $\bar{x}$ and stand $\sigma$ $\bar{x}$.

Any idea how to do this? I am so lost. Even if you can help with just a part of it, it would be much appreciated. Thanks
