Question 2

Correct Answer:

Verified

As a Purchasing Manager,you need to make some decisions regarding the procurement of bolts from three different suppliers: Supplier A,Supplier B,and Supplier C.The diameter at the end of the bolt has specifications of 1.500 ± 0.009 inches.Each of the three suppliers have reported the sample mean and sample standard deviation of their bolt diameters computed from random samples of their production runs.The suppliers' statistics are provided in the following table. a.Based on the sample data provided,what is the value of C_pk for Supplier C? b.Based on the sample data provided,what is the value of C_p for Supplier A? c.Using the sample data provided,if you decide to purchase from the supplier with the greatest value of Cpk,which supplier (A,B,or C)will you choose?

Question 3

Correct Answer:

Verified

a) $C_{p u}=0.014 / .0045=3.11, C_{p l}=.004 / .0045=0.89, C_{p k}=0.89$
b) $C_{p}=0.018 / 0.018=1.00$
c) In computing values of $C_{p k}$ for each of the suppliers, one will notice that the values are smallest for Suppler $B$ and the mean is on target. Therefore, Supplier B is preferable.
