- Answer the following questionarrow_forwardWrite a short notes about system reliability? Subject: Statistical Quality controlarrow_forwardRick Wing, salesperson for Wave SolderingSystems, Inc. (WSSI), has provided you with a proposal forimproving the temperature control on your present machine.The machine uses a hot-air knife to cleanly remove excess solder from printed circuit boards; this is a great concept, butthe hot-air temperature control lacks reliability. According toWing, engineers at WSSI have improved the reliability of thecritical temperature controls. The new system still has the foursensitive integrated circuits controlling the temperature, butthe new machine has a backup for each. The four integratedcircuits have reliabilities of .90, .92, .94, and .96. The fourbackup circuits all have a reliability of .90.a) What is the reliability of the new temperature controller?b) If you pay a premium, Wing says he can improve all fourof the backup units to .93. What is the reliability of thisoption?arrow_forward
