The results shown below are mean productivity measurements (average number of assemblies completed per hour) for a random sample of workers at each of three plants. Research question: Are the mean hourly productivity levels the same for workers in thes three plants? Hourly Productivity of Assemblers in Plants Finished units Produced per Hour 3.4 Plant A (9 workers) B (6 workers) C (1e workers) 3.6 5.1 2.8 4.6 4.7 4.1 2.9 4.5 2.7 3.1 5.0 1.9 2.2 3.2 6.8 2.5 5.4 6.7 4.6 3.9 5.4 4.9 7.1 8.4 Click here for the Excel Data File Fill in the missing data.

Dev Variance Group Plant A Plant B Plant C Total One-Factor ANOVA Source SS df MS p-value Treatment Error Total Based on the hypotheses given below, choose the correct option. Hg: P1 = P2 = 3 H: Not all the means are equal a= 05 O Reject the null hypothesis if pvalue > 0.05 O Reject the null hypothesis if pvalue < 0.05 We reject the null hypotheses. Calculate the mean for each group and the Tukey test statistic Tcale for each pair.
