b) How many students scored marks more than the average marks?​

Answer 1

Answer:

11 students scored higher than average

Step-by-step explanation:

You add all the numbers together then divide by the amount of total numbers. In this case you add all the numbers to get 675. Then you divide 675 by 20 getting 33.75. Now you just count how many students scored higher than 33.75. You would then get 11 students.
