Create a scatterplot of the data. Choose the correct graph
below.
A.
05101520250510152025xy
A scatterplot has a horizontal x-scale from 0 to 25 in intervals
of 1 and a vertical y-scale from 0 to 25 in intervals of 1. Eleven
points are plotted with approximate coordinates as follows: (3, 9);
(4, 6.5); (5, 10); (6, 9); (7, 10.5); (8, 10); (9, 10.5); (10, 2);
(11, 4.5); (12, 10.5); (13, 8).
