Explanation:

Step1: Analyze sophomores' scores

For sophomores, the frequencies are higher for lower - score values (e.g., 1, 2, 3) and decrease as the score increases. So, the tail of the distribution extends to the right.

Step2: Analyze juniors' scores

For juniors, the frequencies are higher for higher - score values (e.g., 4, 5) and decrease as the score decreases. So, the tail of the distribution extends to the left.

Answer:

The distribution of sophomores' scores is right - skewed, and the distribution of juniors' scores is left - skewed.
