The tons handled in a year of the 25 busiest ports in the United States (The 2013 World Almanac) are displayed in the histogram below.

Describe the shape of the distribution.

Approximately what percent lies below 75?

Approximately what are the minimum and maximum of the data set?

What is the center of the dataset? (For this question, take the center to the value with roughly half the years having lower tons handled and half the years having higher tons handled). Be as descriptive as possible.
