1) Get two five number summaries of the **salary** data. Use *summary()* and *quantile()* (with *type=1*). Do they

turn out the same?

What is the mean of these data?

2) Which is larger, the mean or the median? What does this tell you about the skew of the data?

3)Compute the RMS size of the deviations from the mean for these data.

4) Compute the standard deviations using sd(). Do you get the same answer as in the previous problem?
