Q:

Problem Interpreting histogram

I am reading Understandable statistics.
In the second chapter, example 2, the author shows the following histogram:

The author then proceed to interpret the histogram as follows:

About 40% of the wait times fall between 7 and 9 minutes
  while about 80% are between 4 and 9 minutes. Less than 1%
  are 3 minutes or less or greater than 12.

I think that the statement:

Less than 1%
  are 3 minutes or less or greater than 12

is false. It should be:

Less than 10%
  are 3 minutes or less or greater than 12

Is the author correct or am I missing something?

A:

Yes, looking at the graph, $10\%$ seems much more reasonable than $1\%$. It must have been a typo.
