Problem 8

The article Case Study Based Instruction of DOE and SPC (J. Brady and T. Allen, The American Statistician, 2002:312315) describes an effort by an engineering team to reduce the defect rate in the manufacture of a certain printed circuit board. The team decided to reconfigure the transistor heat sink. A total of 1500 boards were produced the week before the reconfiguration was implemented, and 345 of these were defective. A total of 1500 boards were produced the week after reconfiguration, and 195 of these were defective. Find a 95% confidence interval for the decrease in the defective rate after the reconfiguration.

Step-by-Step Solution:
Step 1 of 3

NOTES Week 6 Ch. 15: Permutations. Combinations. The Binomial Distribution factorial: 0! = 1 1! = 1 2! = 2×1= 1 3! = 3×2×1= 6 and so on Permutation: ordered arrangement of “n” distinct items; how many ways we can rearrange a set in order. Ex: {a,b,c} can be rearranged as{b,a,c}{b,c,a}{a,c,b}{c,a,b}{c,b,a}  You can find how many ways to...
