Descriptive Statistics. Using the data used in section 2.6 based on 595 individuals drawn from the Panel Study of Income Dynamics for 1982 and available on the Springer web site as EARN.ASC, replicate the tables and graphs given in that section. More specifically

(a) replicate Table 2.1 which gives the descriptive statistics for a subset of the variables in this data set.

(b) Replicate Figures 2.6–2.11 which plot the histograms for log wage, weeks worked, education and experience.

(c) Replicate Table 2.2 which gives the average log wage for various groups and test the difference between these averages using a t-test.

(d) Replicate Figure 2.12 which plots log wage versus experience. Figure 2.13 which plots log wage versus education and Figure 2.14 which plots log wage versus weeks worked.

(e) Replicate Table 2.3 which gives the correlation matrix among a subset of these variables.
