Concept explainers
a)
To draw: A scatter diagram.
Introduction:
Scatter diagram:
Scatter diagram refers to the tool that shows the relationship between two variables. It is the graphical representation of two variables. In the diagram, one variable is measured on the horizontal axis and other variable is measured on the vertical axis. Scatter points were plotted at the point where both the variable intersects at each other or shows any relation between two variables.

Introduction:
Pareto chart:
Pareto chart is a type of chart that includes lines and bars graph, where individual values are signified in the decreasing order by bars, and the cumulative sum is signified by the line

- Why the quality control officer wants a written record of spoiled materials?arrow_forwardExplain how the control chart can be of use to the manager of the building supplies companyarrow_forwardi) The concept of quality is considered to have evolved through stages. However, quality is used to describe a prestigious product. It is one that fits the intended customer’s requirements. Impliedly, the product should possess attributes that enables it meet the customer’s requirement or specification. 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

The military has exacting quality standards that the con-tractor must meet. The military is very pleased with the quality of the products provided by the contractor andrarely has to return products or has reason for complaint.However, the contractor is experiencing extremely high quality-related costs.
