See if each statement describes the distribution of the data.

green checkmark, The distribution is roughly symmetric.

The left and right sides of the distribution are almost mirror images. So, the distribution is roughly symmetric.

red X symbol, The data has a peak at 10 correct answers.

The column for 8 has the most Xs. So there is a peak at 8 correct answers, not at 10.

green checkmark, The data is spread out from 5 to 10 correct answers.

The leftmost column with an X is 5. The rightmost column with an X is 10. So, the data is spread out from 5 to 10 correct answers.
