Question

identify the distribution as symmetric, left - skewed, or right - skewed.
exam scores for an exam in which most students did very well but a few students failed.
a. left - skewed
b. symmetric
c. right - skewed

Explanation:

In a left - skewed distribution, the tail is on the left side. Here, most students did well (higher scores on the right side of the distribution) and a few failed (lower scores on the left side, creating a left - tail). A symmetric distribution has a balanced shape on both sides. A right - skewed distribution has a tail on the right. Since the situation described has a tail on the left (due to a few low scores while most are high), it is left - skewed.

Answer:

A. Left - skewed
