Prepare a scatter diagram for each of the following pairs of variables and then express in words the apparent relationship between the two variables. Put the first variable on the horizontal axis and the second variable on the vertical axis, a. Age Days absent 28 6 27 7 30 7 33 9 40 4 45 5 41 5 38 2 41 2 1 51 1 48 2 4948 1 1 14 b.
