Roughly symmetric

Single peak

No gaps

Step by step solution

01

 Step 1. Given information.

The dotplot shows the results of rolling a pair of fair, six-sided dice and Page Number: 48 finding the sum of the up-faces 100 times.

02

 Step 2. The shape of the distribution.  

Because the peak in the dotplot is roughly in the middle of the graph, we can conclude that the distribution is roughly symmetric.

We notice that the distribution has a single peak at 7, and there appear to be no gaps in the dotplot.

Roughly symmetric

Single peak

No gaps
