question 50

Four different leadership styles (A, B, C, and D) used by Big-Six accountants were investigated. As part of adesigned study, 15 accountants were randomly selected from each of the four leadership style groups (a total of60 accountants) . Each accountant was asked to rate the degree to which their subordinates performedsubstandard field work on a 10-point scale -- called the ?substandard work scale?. The objective is to comparethe mean substandard work scales of the four leadership styles. The data on substandard work scales for all 60observations were subjected to an analysis of variance. Interpret the results of the ANOVA test shown on theprintout for ? = 0.05. ONE-WAY ANOVA FOR SUBSTAND BY STYLE
$\begin{array} { l | c | r | c | c | c } \text { SOURCE } & \text { DF } &{ \text { SS } } & \text { MS } & \mathrm { F } & \mathrm { P } \\\hline \text { BETWEEN } & 3 & 2800.95 & 933.650 & 4.980 & 0.0039 \\\text { WITHIN } & 56 & 10,498.88 & 187.480 & & \\\text { TOTAL } & 59 & 13,299.83 & & &\end{array}$

• A) At \(\alpha = 0.05\), there is sufficient evidence of differences among the substandard work scale means for the four leadership styles.
• B) At \(\alpha = 0.05\), there is no evidence of interaction.
• C) At \(\alpha = 0.05\), nothing can be said.
• D) At \(\alpha = 0.05\), there is insufficient evidence of differences among the substandard work scale means for the four leadership styles.
