Josie has a number cube that has 30 sides and each side is labeled 1 through 30. She is interested in whether or not the
number cube is a fair cube. Josie performs a simulation which generates 40 trials of 8 rolls of the number cube. She then
graphs the data on a dot plot.
Note: A fair number cube has equally likely outcomes.
Which statement explains how the number cube is fair?
-The data should be symmetric about a central value.
-The data should be skewed left about a central value.
-The data should be skewed right about a central value.
-The data should be randomly distributed.
