essay contest scores
which comparison of the distributions is true?
the distribution of sophomores scores is left - skewed, and the distribution of juniors scores is right - skewed.
both distributions are right - skewed.
both distributions are nearly symmetric.
the distribution of sophomores scores is right - skewed, and the distribution of juniors scores is left - skewed.

Explanation:

Step1: Recall the definitions of skewed distributions

A left - skewed distribution has a tail on the left side. A right - skewed distribution has a tail on the right side.

Step2: Analyze the sophomores' scores (white bars)

Looking at the white bars (sophomores' scores), the tail is on the right side. So the distribution of sophomores' scores is right - skewed.

Step3: Analyze the juniors' scores (blue bars)

Looking at the blue bars (juniors' scores), the tail is on the left side. So the distribution of juniors' scores is left - skewed.

Answer:

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