Define the terms sample size, random sampling, population, and lot size.

Expert Solution & Answer
Check Mark
To determine

Define the terms sample size, random sampling, population, and lot size.

Explanation of Solution

Sample size: As the name suggests, it is essentially the quantity of parts in a sample that need to be inspected. To obtain information about properties of the complete population, parts that are included in the sample are studied.

Random sampling: In this, a sample is selected from a given population where the all the items have equal probability of getting selected.

Population: It is also called universe and it includes the total number of parts that are similar from which a sample is selected.

Lot size: It is the subset of the population where more than one lot can be included in the subsets. They can be reflect the population.

The subject is Engineering Data Analysis
Questions Finite Element Method (FEM) is a great tool to analytical engineering, mostly in mechanical Engineering and Nondestructive testing applications; Finite Element Method cannot exist without the model Data from Computer Aided Draughting. The connection of Computer aided Draughting (CAD) and Finite Element Analysis (FEA) cannot be under played in solving and making predictive analysis. Explain the following school of thought using following set of questions: • What is Finite Element Method? What is FEA? What is CAD? • Explain the types of Analyses that can carried on FEA and CAD 1 when combined together • How does CAD model data Affect FEA output? • Where or which branch/part of Mechanical Engineering does FEM best suit or most applicable and explain why • FEA can further enhance the design or production of machine part , list and explain the parameter that can be optimized. Also Explain the term design optimization. • What are the benefits of FEA? What is the Demerit of FEA? In…
