I am having a hard time with normal distribution. I would be extremely be grateful if you could help me clear my doubt regarding a certain aspect of normal distribution graph.
I have attached the screenshot of a QC problem below. The solution to the problem is option D (Cannot be determined) , however I am getting the average score as 550. Hence option C. Could you please clarify why the final result is option D and not C?
Best, Manish A.Shetty
