There were 855 major league baseball players in 2012 and their mean salary was $m=3.44$ million dollars with standard deviation $s=4.70$ million dollars.If we take random samples of size $n=30$ players and calculate the mean salary, in millions of dollars, of each sample, describe the shape, center, and standard error of the distribution of sample means.

Step 1
If a sample is drawn =, then the sample will follow normal distribution because all the sampling distributions approximately follows the normal distribution with mean, m and standard deviation, $\sqrt{n}$.
Therefore, the shape of distribution is approximately symmetric.
Step 2
The mean is same, i.e. $m=3.44$ million dollars and the standard error is,
$SE=\frac{8}{\sqrt{n}}$
$\frac{4.7}{\sqrt{30}}=0.8581$ milion dollars
