We know the image has few pure black areas, few pure white areas, and is mostly composed of middle tones.
That's either an overexposed low-key image, an underexposed high-key image, or is a reasonably exposed medium-key image.
We can tell that there's large areas of similar coloring, in a slightly dark, slightly cool tone, as there are narrow peaks that are close together in the lower quartertones.
We still don't know if it's properly exposed from the histogram alone.
From the histogram and the image, we can say it's probably properly exposed
