Answer
Positive correlation
Work Step by Step
We use a graphing calculator to plot the points $(x,y)$, where $x$ represents the number of years after $1988$ (calculated from row $1$ in the given table) and $y$ represents the shipment of CDs (row $3$ in the given table).
From the graph we notice that when $x$ increases, $y$ increases, so the correlation between the year and the shipment of CDs is $\text{positive}$.
