Expert Solution
Step 1

The provided histogram displays a symmetrical distribution of data.

If the data are symmetric, they have about the same shape on either side of the middle. In other words, if you fold the histogram in half, it looks about the same on both sides. Histogram in the figure shows the mean and median are close together. 

A distribution is symmetrical if a vertical line can be drawn at some point in the histogram such that the shape to the left and the right of the vertical line are mirror images of each other.

The mean, the median, and the mode are each seven for these data.   

  (i) (ii)
Mean 7 7
Median 7 7
Mode 7 7
