The distributions are not symmetric.
Similarities: Both classes have the highest number of students with one pet, and both classes show a decrease in the number of students as the number of pets increases to four.
Differences: Mr. Bernhardt's class has students with zero pets, while Ms. Daniels' class does not. Additionally, Ms. Daniels' class has more students with three pets compared to Mr. Bernhardt's class.
I determined the symmetry by observing the frequency of pets each student has, noting that Mr. Bernhardt's distribution has a peak and tails on both sides, while Ms. Daniels' distribution is skewed with no students having zero or four pets.
