The areas, in cm², of some circuit boards are represented in the following graph.

a. State the greatest possible range of the data.

b. Construct a box-and-whisker diagram to illustrate the data.

c. Find the range of the middle 60% of the areas.

d. An outlier is an extreme value that is more than 1.5 times the interquartile range above the upper quartile or more than 1.5 times the interquartile range below the lower quartile. Find the areas that define the outliers in this set of data, and estimate how many there are. How accurate is your answer?
