Use the following narrative and partial One-way ANOVA results shown below to answer questions 15 – 16. A one-way ANOVA was carried out to determine whether management styles (Authoritarian, Laissez Faire, and Participative) differ among organizations and may potentially affect employee’s job satisfaction. The employees were asked to rate their level of job satisfaction on a 10-point scale. Source DF SS MS F Factor * 87.40 * * Error 27 37.40 * Total 29 * Based on the partial One-way ANOVA results shown above, which of the answer choices is closest to the F test statistic value? Round to two decimal places
