You're probably having debate because the premise of the question is
broken. The "9am average" doesn't make any sense -- 9am only represents
9:00:00 to 9:00:59. Or, in terms of your answers, 9:00:00 - 9:59:59 AM =
the 9 o'clock hour.

What you're plotting is really a histogram of the data in bins of time
(i.e., an average of the data, not an average of the time). 'The average
between 9am & 10am was X' is what I think you're really trying to say.
So, you should either label each bin 9-10, 10-11, 11-12, etc. or just
label the tick marks between each bin.

Regards, Adam
