Answer 1

1. A. linear association and D. positive association

2. A. linear association and D. positive association

Explanation:

Linear association occurs when the points in the plot can be well represented by a line .

Positive association occurs when an increment in one variable implies an increment in the other one. For example, in the second case, p increments from 1 to 2 and q increments from 1 to 11.

The plot of the second case is shown in the figure attached.
