The temperature on a July day starts at 60 degrees at 8 a.m. and rises
steadily to 96 degrees at 8 p.m.

\begin{enumerate}
\item Why can't you say with certainty that the average temperature
between 8 a.m. and 8 p.m. was 78 degrees?

\vfill

\item What can you say about the average temperature during this 12
hour period?

\vfill
\item Suppose you also know that the average temperature during this
period was 84 degrees. Is it possible that the temperature was 80
degrees at 6 p.m.? At 4 p.m.?
