Explain the purposes and formulas of the range, the interquartile range, and the semi- interquartile range Solution The semi-interquartile range is a measure of spread or dispersion. It is computed as one half the difference between the 75th percentile [often called (Q3)] and the 25th percentile (Q1). The formula for semi-interquartile range is therefore: (Q3-Q1)/2. Since half the scores in a distribution lie between Q3 and Q1, the semi-interquartile range is 1/2 the distance needed to cover 1/2 the scores. In a symmetric distribution, an interval stretching from one semi-interquartile range below the median to one semi-interquartile above the median will contain 1/2 of the scores.x range = vo² sin2 /g Where: vo = launch velocity = launch angle; sin2 = sin(2 * ) g = acceleration of grav.

1. Explain the quality assurance plan, emphasizing on the ways to manage, monitor, and control
quality.
Analyze the impact of this project on meeting cost targets set by the company. Think about the
cost-benefit analysis, the cost of conformance, and the cost of nonconformance.
Explain how you will work to minimize the implications on cost.Project Quality and Cost
Management
You are a procurement and supply manager at a company that manufactures and assembles
construction equipment. A warranty reduction project has identified that one of the components
a supplier is producing is not conforming to the technical drawing. As a result of the
nonconforming component, customers have experienced downtime in the field. As part of the
warranty reduction project, you are challenged with implementing a quality assurance plan for
the component to ensure that quality is not compromised in the future.
Based on the above scenario:

Solution
Quality Assurance Plan-
Quality Assurance Plan is a critical part of any project, as it enables to agree a set of quality
targets with the customers. It then helps in monitoring and controlling the level of quality, which
further indicates the level of adherence to the targets. The purpose of quality assurance plan is to
direct and facilitate the establishment of quality assurance activities with in processes used to
deliver right products and services to the clients. This also makes sure of the quality of the goods
delivered.
Policy
Quality Assurance Plan describes the principles, processes and procedures used to support the
regular delivery of high quality products and competitive services. The quality assurance process
is concerned with establishing the authority of the quality assurance function, standards,
procedures and their monitoring and evaluation to determine quality in relation to established
standards. Quality assurance activities concentrate on the prevention of problems through the
