Two different types of polishing solution are being evaluated for possible use in a tumble-polish operation for manufacturing intraocular 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. Construct a 99% confidence interval p1-p2.

Two different polishing materials are being evaluated for use in machining operations in a manufacturing company. One hundred machine parts were polished using polishing material A and of this number 87 had no polishing-included defects. Another 100 machine parts were polished using polishing material B and 75 parts were satisfactory upon completion. Is there any reason to believe that the two polishing materials differ? Use α = 0.02.

Two grocery store checkout systems are being evaluated for adoption by a national supermarket chain. One of the two systems was set up for testing in an Ormond Beach, Florida store while the other was set up in Portland, Oregon. A sample of 120 customers in the Florida store showed a mean checkout time of 4.1 minutes. An independent sample of 100 customers from the Oregon store yielded a mean checkout time of 3.4 minutes. Historical data maintained by the...
