Given below are the analysis of variance results from a Minitab display. Assume that you want to use a 0.05 significance level in testing the null hypothesis that the different samples come from populations with the same mean.
-$$\begin{array} { l r c l c c }
\text { Source } & \text { DF } & \text { SS } & \text { MS } & \text { F } & \text { p } \
\text { Factor } & 3 & 13.500 & 4.500 & 5.17 & 0.011 \
\text { Error } & 16 & 13.925 & 0.870 & & \
\text { Total } & 19 & 27.425 & & &
\end{array}$$ Identify the p-value.
A)0.011
B)4.500
C)5.17
D)0.870

The p-value is given directly in the Minitab output under the "p" column, corresponding to the "Factor" row, which is 0.011. This value is used to determine if the difference between means is statistically significant.
