Songs on an iPod David’s iPod has about 10,000 songs. The distribution of the play times for these songs is heavily skewed to the right with a mean of 225 seconds and a standard deviation of 60 seconds.

Suppose we choose an SRS of 10 songs from this population and calculate the mean play time x– of these songs. What are the mean and the standard deviation of the sampling distribution of x–? Explain.
