Answer:
The mean score is 7.31. This means that each time the student takes this test, he is expected to get a score of 7.31.
Step-by-step explanation:
We have these following probabilities:
A 0.07 = 7% probability that the student scores 5 points.
A 0.17 = 17% probability that the student scores 6 points.
A 0.38 = 38% probability that the student scores 7 points.
A 0.21 = 21% probability that the student scores 8 points.
A 0.1 = 10% probability that the student scores 9 points.
A 0.07 = 7% probability that the student scores 10 points.
Mean score
We multiply each score by it's probability. So
The mean score is 7.31. This means that each time the student takes this test, he is expected to get a score of 7.31.
