Question

Four quiz scores are 79, 84, 81, and 73. Which score is closest to the mean of the four scores?

A) 79
B) 84
C) 81
D) 73​

Answer 1

Answer: A

Explanation:

We must calculate the mean and compare each score to find the score closest to the standard of the four scores (79, 84, 81, and 73).

Mean = (79 + 84 + 81 + 73) / 4 = 317 / 4 = 79.25

Now, let's compare each score to the mean:

Distance from the standard for 79: |79 - 79.25| = 0.25

Distance from the standard for 84: |84 - 79.25| = 4.75

Distance from the standard for 81: |81 - 79.25| = 1.75

Distance from the standard for 73: |73 - 79.25| = 6.25

The score with the smallest distance from the average is 79, closest to the standard.

Therefore, the correct answer is:

A) 79
