Answer:

Step-by-step explanation:

Given that a college senior who took the Graduate Record Examination exam scored 530 on the Verbal Reasoning section and 600 on the Quantitative Reasoning section.

Quantitative reasons scores are N (429, 148)

Hence Z score for the college senior = $\frac{530-429}{148} \\=0.6824$

The mean score for Verbal Reasoning section was 460 with a standard deviation of 105

Verbal reasoning score was N(460, 105)

The score of college senior = 530

Z score for verbal reasoning = $\frac{530-460}{105} \\=0.6667$

comparing we can say he scored more on quantiative reasoning.

Thus comparison was possible only by converting to Z scores.
