1. Problem Description
The image contains four multiple-choice questions related to statistical process control, statistical quality control, statistical thinking process, and measurement scales. The questions need to be answered based on the provided options.
2. Solution Steps
Question 1:
Statistical Process Control (SPC) tools are used to monitor and control a process. They don't necessarily ascertain if the inputs/outputs *meet* a standard. They help to identify deviations from the standard.
Therefore, the answer is False.
Question 2:
Statistical Quality Control (SQC) indeed helps monitor process behavior, discover issues, and find solutions for production issues.
Therefore, the answer is True.
Question 3:
The steps in a statistical thinking process typically include:
1. Develop a clear and concise description of the problem.
2. Propose a model for the problem using scientific knowledge.
3. Collect data and test hypotheses.
Guessing a solution is not a standard procedure in statistical thinking. Instead, data should drive the solution. Thus, III is not a standard procedure. We seek to find which of the provided options is *not* a standard procedure. Options I and II are typically standard procedures. Hence, we need to pick the option that is missing in the list, which is III. Therefore we are seeking for something which has item III inside.
Therefore, the correct answer is A, I and II only since they are the standard ones. Thus, option C, II and III only, should be the best choice since the question is asking EXCEPT.
Question 4:
A measurement scale with an ordered relationship, a unique identity, and equal intervals between units is an interval scale. An ordered relationship implies that the data can be ranked. A unique identity means that each value is distinct. Having equal intervals is what distinguishes it from an ordinal scale. A ratio scale also has these properties, but also has a meaningful zero point.
Therefore, the answer is B. Interval Scale.
