Answer 1

Adding these 5 points will have no effect on the shape of the distribution of scores.

What is an average?

Average is a measure of central tendency. It is determined by adding the total observations and dividing it by the total number of observations. For example, if the sum of scores on the test is 680 and there are 10 students, the average score would be 68.
