1. We are given a table and asked to find which statements are true, and which are false.

2. The commodity with the greatest percent decrease over the year from October 2011 to October 2012 showed an increase in three of the four months shown. Looking at the greatest percent decrease over the year, we see that the commodity is natural gas (-20.5). In the columns for 4 months, we see that exactly 3 of the months have a positive percent change. So, the statement is true.

3. The commodity that showed a decrease for all four months had the lowest index value in the group for October 2012. The commodity with a negative percent change in all 4 months is paper and paper-base stocks. However, it didn't have the lowest index - 112.7 - instead of 81.1. So, the statement is false.

4. The commodity with the median index in the group for September 2012 was also the median for October 2012. The median index for October was 119.5 and for September it was 119.3. Both belonged to the commodity electric generating equipment. So, the statement is true.
