Answer 2

The correct answer is B) There is a gap in Plot A, but not in Plot B

Step-by-step explanation:

A dot plot is a type of graphic used in statistics to show information collected about a group of subjects or elements. In this, each dot or circle represents a subject related to a specific scale for example, in the case presented, the scale is the number of hours subjects watched television.

According to this, the statement that is true about the dot plots presented is that there is a gap in plot A because most subjects reported watching television for 3 to 7 hours; however, one of the subjects watched television 10 hours. This implies, a gap or space in the graphic because there is an interval in the scale with no subjects as most are grouped in a cluster except by one. This does not occur in plot B because all subjects form one cluster or group.
