Answer:
The average points received by those students who did not pass the test successfully would be 4 points.
Explanation:
Step 1: We know that all students wrote the test and received an average of 6 points.
Step 2: We also know that 60% of those students passed the test successfully and received an average of 8 points.
Step 3: This means that the remaining 40% of students did not pass the test successfully.
Step 4: Since the average points for all students was 6 points and the average points for those who passed the test was 8 points, the average points for those who did not pass the test would be 4 points.
