Answer:
D, a pareto diagram
Explanation:
The pareto diagram was named after the discoverer of the diagram/technique, Vilfredo Pareto. He used the diagram in his study of wealth and poverty in Europe in the 1900s.
The pareto diagram is a bar chart that ranks related events in decreasing other of occurrence. It contains both a bar and line graph. The individual events are recorded by the bar while the total event is recorded by the line graphs.
In the above question, for Clarissa to identify defects, she has to use Pareto diagram which will have the defects represented by the bar and the total production process by the line graph. This helps her to find out the stage in production where the defects started from and how much effect it has onn the production process.

Answer:
a: 12.8%
Explanation:
Standard Deviation would be calculated with the probability approach since there is probability given in the question.
- Formula of Standard Deviation and the solution is given in the pictures below.
- Although ERR the required part to calculate Standard Deviation is calculated in the text.
Calculating ERR:
ERR= Sum of Probabilities × Rate of returns.
In our question = ERR= 0.2 × 30% + 0.5 × 10% + 0.3 × (-6%) = 0.128 = 12.8%
Thus, by putting all the values in the formula you will get the answer 12.8%.
