Confussion in the Question of Quality Quiz(lesson seven) last question

While I was going through Coach Andrew's Course, I was bit confused of the below question in the (lesson 7 Quality Quiz Question ) and I compared the answer with chatGPT and found there is a difference as below :-

The project manager has met the project team, and they have created a control chart to determine whether the quality processes are stable and if it needs to be improved. They have taken a sample of 30 deliverables that are produced in a row and have identified that six of them are consecutively above the middle line between the upper and lower limits. What should the project team do next?

Nothing the process is in control

Implement a change request to fix the process

Report to defect to the project sponsor

Create an Ishikawa diagram to identify the reasons for the defect

Correct answer

Nothing the process is in control

The ChatGPT is providing the below answer.

Given that six consecutive deliverables are above the middle line on the control chart, this indicates a potential issue with the process. The best course of action would be to create an Ishikawa diagram (also known as a fishbone diagram) to identify the root causes of the defect. This tool helps in systematically analyzing the factors contributing to the problem, allowing the team to address the underlying issues effectively.

Can you explain in details if the time permits.
