A group of20 recently hired sales trainees were randomly assigned to one of four different ?home rooms? - five traineesper room. Each room is identical except for wall color. The four colors used were light green, light blue, grayand red. The psychologist wants to know whether room color has an effect on attitude, and, if so, wants tocompare the mean attitudes of the trainees assigned to the four room colors. At the end of the trainingprogram, the attitude of each trainee was measured on a 60-pt. scale (the lower the score, the poorer theattitude) . The data was subjected to a one-way analysis of variance. At ? = 0.05, what would be the bestinterpretation? ONE-WAY ANOVA FOR ATTITUDE BY COLOR
$\begin{array} { l | c | r | r | r | r } \text { SOURCE } & \text { DF } & { \text { SS } } & { \text { MS } } & \mathrm { F } & \mathrm { P } \\\hline \text { BETWEEN } & 3 & 1678.15 & 559.3833 & 59.03782 & 0.0000 \\\text { WITHIN } & 16 & 151.6 & 9.475 & & \\\text { TOTAL } & 19 & 1829.75 & & &\end{array}$

• A) At \(\alpha = 0.05\), it can be said that color doesn't matter
• B) At \(\alpha = 0.05\), light green has a higher mean than gray
• C) At \(\alpha = 0.05\), it can be said that at least one color has a different mean
• D) At \(\alpha = 0.05\), red is the best color
