A laser produced is not working properly after a quality control
experiment. Explain the causes of the problem. Describe the
requirements needed to produce efficient lasers using diagrams.
19. According to one of the Western Electric rules for quality
control, a produced item is considered conforming if its
measurement falls within three standard deviations from the target
value. Suppose that the process is in control so that the expected
value of each measurement equals the target value. What percent of
items will be considered conforming, if the distribution of
measurements is
(a) Normal(μ, σ)? (b) Uniform(a, b)?
If the Shops applied the Trilogy of Juran; “Quality Planning,
Quality Control and Quality Improvement,” explain what the
shop-owners should have been seen doing?
Explain the construction and working of a CO2 laser with a
suitable energy level diagram.
Find the ratio of the population of the two states in a He–Ne laser
that produces light of
wavelength 632.8 nm at 27C
In a quality control
test of parts manufactured at Dabco Corporation, an engineer
sampled parts produced on the first, second, and third shifts. The
research study was designed to determine if the population
proportion of good parts was the same for all three shifts. The
test to be used is a chi-square test of homogeneity using a
significance level α=0.05.

a) Explain the major causes of kick as related to the well
control.
b) There are two major methods usually used in killing the
well "the driller method" and "wait and weight method." Suppose
that you have the following situation. Which method you will
choose. Explain and justify your answer.
• Shortage of crew members for mixing.
• Shortage of heavy material (Barite) to prepare a kill
mud.
• Un-skillful people to do a complicated calculation.
• Time is...
A factory that manufactures bolts is performing a quality
control experiment. Each object should have a length of no more
than 17 centimeters. The factory believes that the length of the
bolts exceeds this value and measures the length of 56 bolts. The
sample mean bolt length was 17.04 centimeters. The population
standard deviation is known to be σ=0.22 centimeters. What is the
test statistic z? What is the p-value? Does sufficient evidence
exist that the length of bolts is...
A factory that manufactures bolts is performing a quality
control experiment. Each object should have a length of no more
than 20 centimeters. The factory believes that the length of the
bolts exceeds this value and measures the length of 64 bolts. The
sample mean bolt length was 20.06 centimeters. The population
standard deviation is known to be σ=0.16 centimeters.
What is the test statistic z?
What is the p-value?
Does sufficient evidence exist that the length of bolts is...

Explain causes leading to the plastic straps on a lawn chair
seat, break after it has been left in sunlight for a long period of
time. What types of additive can be used to prolong the life of the
straps?
For at least four of Ishikawa’s seven basic tools for quality
control, explain how the tool could be used to help explain the
results from the collection of some metric data. That is, for each
of the selected tools, give an example of some metric data you have
collected and explain how the tool (diagram) could be used to help
understand the data.
