A heart valve manufacturer has three different processes for producing a leaf of an artificial heart valve.
Random samples of 50 valves were selected five times from each type of manufacturing process.
Each valve was tested for defective opening mechanisms. The number of defective valves in each sample of 50
is summarized in table below.
