how would you describe the shape of the distribution?
uniform
bell - shaped (unimodal and symmetric)
skewed left
skewed right
multimodal

Explanation:

A bell-shaped (unimodal and symmetric) distribution has a single peak, with data evenly distributed on both sides of the peak, matching the histogram shown where the highest frequency is in the center and frequencies taper off symmetrically to the left and right. A uniform distribution has equal frequencies across all bins, left-skewed has a tail on the left, right-skewed has a tail on the right, and multimodal has multiple distinct peaks, none of which match the given histogram.

Answer:

Bell-shaped (unimodal and symmetric)
