Using the following one-way ANOVA summary table, what is the researcher's conclusion, and what possible error is attached to this decision? (? = .05) $\begin{array}{|l|l|l|l|l|l|}
\hline \text { Source of variation } & \text { SS } & \text { df } & \text { MS } & \text { F } & \text { P } \
\hline \text { Between } & 200 & 4 & \text { B } & \text { D } & .01 \
\hline \text { Within } & \text { A } & 80 & \text { C } & & \
\hline \text { Total } & 1000 & & & & \
\hline
\end{array}$
A) Retain the null hypothesis, Type I error
B) Retain the null hypothesis, Type II error
C) Reject the null hypothesis, Type II error
D) Reject the null hypothesis, Type I error

The researcher should reject the null hypothesis because the p-value (.01) is less than the significance level (.05). Therefore, there is evidence to suggest that there is a significant difference between the means of the groups being compared. The possible error attached to this decision is a Type I error, which occurs when the null hypothesis is rejected even though it is true.
