Draw a time-series graph of the quantity of compact discs sold. Say in which year or years the quantity sold

(a) was highest,

(b) was lowest,

(c) increased the most, and

(d) decreased the most. If the data show a trend, describe it.

The spreadsheet in Table 1 provides data on the U.S. economy: Column A is the year; the other columns are quantities sold in millions per year of compact discs (column B), music videos (column C), and singles downloads (column D). Use this spreadsheet to work Problems 1 and 2.
