Question 188974: 11.26 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 these three plants? Productivity
Hourly Productivity of Assemblers in Plants
Plant Finished Units Produced Per Hour
A (9 workers) 3.6 5.1 2.8 4.6 4.7 4.1 3.4 2.9 4.5
B (6 workers) 2.7 3.1 5.0 1.9 2.2 3.2
C (10 workers) 6.8 2.5 5.4 6.7 4.6 3.9 5.4 4.9 7.1 8.4

--------------------------------------------------
Ho: the means are all the same
Ha: at least one of the means is different
---------------------
Run an ANOVA test on the lists of A, B, C data
If the p-value is less than 5% reject Ho and accept
Ha.
