Six observations were selected from each of three populations. The data obtained is shown below.
$\begin{array}{lll}\text { Sample } 1&\text { Sample } 2&\text { Sample } 3\
31 & 31 & 37 \
28 & 32 & 36 \
34 & 33 & 39 \
32 & 30 & 40 \
26 & 32 & 35 \
29 & 34 & 35
\end{array}$
a. Compute the overall sample mean .
b. Test at the α = 0.05 level to determine if there is a significant difference in the means of the three populations.
