hypothesis test including checking (explaining why) the assumptions are met.

3) One way to improve a process is to eliminate non-value-added activities and wasted effort. A consultant was hired to improve the efficiency in a large shop floor operation. She tested three different workspace designs and measured the process flow time (in days) for each design. The data

from her experiment is in the Excel document titled "Workspace Design" in Moodle. Is there evidence that any of these workspaces impact process flow time? If so, which workspace design is best? Test this at a 1% significance level.
