Note: It's hard to read graphs absolutely precisely, so allow a little bit of latitude in the answers below.

- 107-68=39 degrees
- Antarctica. You can do the math here, finding the average for the 12 months, but as Antartica's average temperature is the lowest in all but 4 months, it will definitely be the lowest average.
- Saudi Arabia. You can find all of the datapoints and line them up to find the medians, but as almost all of Saudia Arabia's temperatures are higher than any of Siberia or Antarctica's temperatures, Saudi Arabia will definitely have the highest median.
- 37 degrees. Saudi Arabia in July is about 107 degrees. Siberia in July is about 70. $107-70=37$.
- 105 degrees. Siberia in May is about 40 degrees and Antarctica in May is about -65. $40-(-65)= 105$ degrees.
- Siberia. You can subtract the minimum from the maximum of each region to find each region's range, but you can see that Siberia's temperature changes the most. It has the highest range.
- Saudi Arabia. Saudi Arabia's range is $107-68=39$ degrees and Antarctica's range is $-15-(-68)=53 degrees$.
- Both Saudia Arabia and Siberia have their highest average high temperatures in the summer months, so they are in the northern hemisphere. Antarctica has its highest average high temperatures in the winter months, so it is in the southern hemisphere.
