□ gabriel has a slightly higher quiz average than noah.
□ noah is a better test taker than gabriel.
□ noah has more variation in his quiz scores.
□ gabriel has more variation in his quiz scores.

Explanation:

Step1: Compare mean scores

Noah's mean = 87, Gabriel's mean = 87.17. $87.17 > 87$

Step2: Compare variation metrics

Noah's range = 8, MAD = 2.67; Gabriel's range = 12, MAD = 3.22. $12 > 8$, $3.22 > 2.67$

Step3: Evaluate unsupported claims

No data supports "better test taker" claim. Noah's variation is lower, not higher.

Answer:

Gabriel has a slightly higher quiz average than Noah.
Gabriel has more variation in his quiz scores.
Gabriel's quiz scores are more spread out than Noah's quiz scores.
