13/8 = 1 5/8
Since 13/8 = 1 5/8, A and B cannot be correct.
5/8 > 1/2
Since 5/8 > 1/2, 13/8 is closer to 2 than to 1. Therefore, the answer is D. closer to 2 than to 1.

Answer:
c. the biology test
Step-by-step explanation:
To answer this problem we need to calculate the z-score of both tests, using the formula:
z = (x - μ) / σ
Where x is Sue's score, μ is the mean, and σ is the standard deviation.
- For the <u>biology test</u>, the z-score is:
z = (76 - 70) / 7 = 6/7 = 0.857
- For the <u>math test</u>, the z-score is:
z = (76 - 75) / 10 = 1/10 = 0.100
Because the z-score for the biology test is greater than the z-score for the math test, Sue did better in the biology test, in comparison to the rest of the class.
