Suppose we record the husband’s age and the wife’s age for many randomly selected male female married couples. Since these are both quantitative variables, we create a scatterplot for the data, with wife’s age on the horizontal (X) axis and husband’s age on the vertical (Y) axis. Describe the characteristics of a case in each of the following locations in the scatterplot:

(a) The top left corner.

(b) The top right corner.

(c) The bottom left corner.

(d) The bottom right corner.
