The box plots show the average daily temperatures in January and December for a U.S. city:

two bar graphs shown. The top one is labeled January. Minimum at 0, Q1 at 10, median at 12, Q3 at 13, maximum at 16. The bottom bar graph is labeled December games. Minimum at 1, Q1 at 5, median at 18, Q3 at 25, maximum at 35

What can you tell about the means for these two months?

The mean for December is higher than January's mean.

It is almost certain that January's mean is higher.
There is no way of telling what the means are.
The narrow IQR for January causes its mean to be lower.
