Which statement correctly compares the shapes of the
distributions ?
Standardized tests for certain subjects, given to high
school students, are scored on a scale of 1 to 5. Let A
represent the score on a randomly selected exam for
subject A and let B represent the score on a randomly
selected exam for subject B. The distributions of scores
for each subject's standardized tests are displayed in the
table and the histograms.

Subject A's distribution is skewed right and subject
B's distribution is skewed lett.
O Subject A's distribution is roughly unimodal
symmetric and subject B's distribution is skewed left.
