Concept explainers
a)
To determine: The fraction defective in each sample.
Introduction: Quality is a measure of excellence or a state of being free from deficiencies, defects and important variations. It is obtained by consistent and strict commitment to certain standards to attain uniformity of a product to satisfy consumers’ requirement.
b)
To determine: The estimation for fraction defective when true fraction defective for the process is unknown.
Introduction: Quality is a measure of excellence or a state of being free from deficiencies, defects and important variations. It is obtained by consistent and strict commitment to certain standards to attain uniformity of a product to satisfy consumers’ requirement.
c)
To determine: The estimate of mean and standard deviation of the sampling distribution of fraction defective for samples for the size.
Introduction:
Control chart:
It is a graph used to analyze the process change over a time period. A control chart has a upper control limit, and lower control which are used plot the time order.
d)
To determine: The control limits that would give an alpha risk of 0.03 for the process.
Introduction:
Control chart:
It is a graph used to analyze the process change over a time period. A control chart has a upper control limit, and lower control which are used plot the time order.
e)
To determine: The alpha risks that control limits 0.47 and 0.003 will provide.
Introduction:
Control chart:
It is a graph used to analyze the process change over a time period. A control chart has a upper control limit, and lower control which are used plot the time order.
f)
To determine: Whether the process is in control when using 0.047 and 0.003.
Introduction:
Control chart:
It is a graph used to analyze the process change over a time period. A control chart has an upper control limit, and lower control which are used plot the time order.
g)
To determine: The mean and standard deviation of the sampling distribution.
Introduction:
Control chart:
It is a graph used to analyze the process change over a time period. A control chart has a upper control limit, and lower control which are used plot the time order.
h)
To construct: A control chart using two sigma control limits and check whether the process is in control.
Introduction:
Control chart:
