Question 1
10/ 10 pts
At an electronic manufacturing company, the quality manager of a process improvement project
measures the weight of TV screens by weighing a sample of five randomly picked TV screens daily. The
manufacturing process is currently considered to be in control, with the standard deviation of sample
means equaling 0.45 inches. The results of the last four days are presented in the attached table.

verifier=XW7zXrWghWJUei6zhMnAUwltdUnnab5gm8D5pgnn&wrap=1) Calculate the upper control limit
(UCL) and the lower control limit (LCL) for the mean chart assuming that the company is using a 3-sigma
process model. Round to the nearest hundredth.
Correct!
(26.58, 29.28)
(27.62, 29.28)
(26.64, 28.91)
(24.85, 29.45)
UCL = 29.28; LCL = 26.58. Find the mean for each day. For example, the mean for Day 1 mean = (28.91
+ 26.64 + 27.64 + 28.90 + 28.46)/5 = 28.11. The means for Day 1 to Day 4 28.11, 28.34, 27.66, and
27.62, respectively. To find the center line, average the sample means: X-double-bar = 27.93.
For a 3-sigma model, UCL = X-double-bar + 3*s = 27.93 + (3 x 0.45) = 29.28.
LCL = X-double-bar -(3 x s) = 27.93 -(3 x 0.45) = 26.58.
Question 2
10/ 10 pts
According to Garvin's definition of quality, quality is found in the components and attributes of
a product.
Transcendent
Manufacturing-based
Correct!
Product-based
Value-based
Garvin found that most definitions of quality were transcendent, product-based, user-based,
manufacturing-based, or value-based. According to the product-based definition, differences in quality
amount to differences in the quantity of some desired ingredient in or attribute of the product.
