# Expand Your Knowledge: Dotplot another display technique that is somewhat similar to histogram is dotplot . In a dotplot, the data values are displayed along the horizontal axis A dot is then plotted over each data value in the data set. (a) Form the dotplot, how many states have 600 or fewer licensed drivers per 1000 residents? (b) About what percentage of the states (out of 51) seem to have close to 800 licensed drivers per 1000 residents? (c) Consider the intervals 550 to 650, 650 to 750, and 750 to 850 licensed drivers per 1000 residents. In which interval do most of the states fall?
