Spam and !!! interpretation

Which interpretation of these faceted histograms is not correct?

50 XP

The most common value of exclaim_mess in both classes of email is zero (a log(exclaim_mess) of -4.6 after adding .01).

There are more cases of spam in this dataset than not-spam.

Even after a transformation, the distribution of exclaim_mess in both classes of email is right-skewed.

The typical number of exclamations in the not-spam group appears to be slightly higher than in the spam group.
