a. symmetric distribution
b. negatively skewed distribution
c. positively skewed distribution

1.
2.
3.

Explanation:

Analyze the first histogram

Using the Histogram Shapes and Skewness of Distribution knowledge points

• The peak of the red distribution is located on the left side (around 180).
• The tail of the distribution extends further to the right (towards 230).
• A distribution with a long tail on the right side is positively skewed.

Analyze the second histogram

Using the Histogram Shapes and Skewness of Distribution knowledge points

• The peak of the blue distribution is located on the right side (around 210).
• The tail of the distribution extends further to the left (towards 160).
• A distribution with a long tail on the left side is negatively skewed.

Analyze the third histogram

Using the Histogram Shapes and Symmetric Distribution knowledge points

• The pink distribution is centered around the middle bar.
• The left and right sides of the distribution are approximately mirror images of each other.
• A balanced distribution with symmetric tails is a symmetric distribution.
