Two different types of polishing solutions are being evaluated for possible use in tumble-polish operation for manufacturing interocular lenses used in the human eye following cataract surgery. Three hundred lenses were tumble polished using the first polishing solution, and of this number, 253 had no polishing-induced defects. Another 300 lenses were tumble-polished using the second polishing solution, and 196 lenses were satisfactory upon completion. Is there any reason to believe that the two polishing solutions differ? Use a = 0.01.

Two different types of polishing solutions are being evaluated for possible use in tumble-polish
operation for manufacturing interocular lenses used in the human eye following cataract surgery.
Three hundred lenses were tumble polished using the first polishing solution, and of this number,
253 had no polishing-induced defects. Another 300 lenses were tumble-polished using the
second polishing solution, and 196 lenses were satisfactory upon completion.
Is there any reason to believe that the two polishing solutions differ? Use a = 0.01.
