Introduction:
Scatter diagram refers to the graph which are used to indicate the relationship between two variables.
(b)
To determine:
Whether therelationship between permeability and carbon content can be established or not.
Introduction:
The relationship between permeability content and the carbon content can be better understand with the help of the scatter diagram.
(c)
To explain:
The data that the scatter diagram will represent with respect to the carbon content if the low permeability is advantageous.
Introduction:

- In a car manufacturing company, an automated painting process has been introduced, and the quality assurance team suspects there might be issues that require investigation. The team decides to conduct a root cause analysis to identify potential problems. Through the root cause analysis and further investigation, it appears that the drying time of the paint in minutes is affecting the overall quality of the finish. The aspect they need to examine is the variation in drying time across different colours of paint. Considering the ongoing concerns in the painting process, the team chooses to collect a sample of six drying time measurements every 20 minutes from various colours of paint. The recorded drying time values for a day's production are presented in Table 1. A total of 10 sets of measurements, each consisting of six drying time values in minutes, have been collected. Each time a set of measurements is taken, the individual drying time values are recorded.

Now, in identifiably distinctive manner, differentiate quality control from the others or quality assurance. ii) Briefly define hazard, when uncertainty is defined as being a situation in which the determination of risk factors is not possible. It is difficult therefore to calculate the effect of uncertainty upon the tender, and a discussion of uncertainty is out of place here. A builder will see risks in two distinct categories: (a). those that can be insured against and,( b). those that cannot be insured against.arrow_forward
