Question 1

A manufacturing firm wants to apply 6-sigma standards to its automated tolerance-check process. Suppose that each scanner makes the correct decision only 50% of the time, however only 1 correct decision by any scanner makes the entire process a success. How many scanners are needed to ensure 6-sigma quality?

Question 2

A product design team is preparing to build a new doohickey. A doohickey consists of one A module, one B module, and one C module. There are different versions of these modules available in the company's design library. For example, there are two choices for A: A1 is .99 reliable, while A2 is .975 reliable. The table below details the choices available, along with the cost of each choice.

Module variation	Reliability	Cost, each
A1	.99	$17
A2	.975	$10
B1	.995	$4
B2	.992	$3
C1	.98	$2
C2	.90	$0.50
C3	.60	$0.25

Help the design team by selecting the least costly version of a doohickey that has system reliability of at least .96. Draw a schematic of your finished design.
