1. which of these histograms is approximately normally distributed?

Explanation:

A normal distribution's histogram is symmetric and bell - shaped, with frequencies increasing to a peak and then decreasing symmetrically.

• For the first histogram: It has a single peak, and the frequencies on either side of the peak seem to be roughly symmetric.
• For the second histogram: The left - hand side (lower scores) has a different pattern of frequency increase compared to the right - hand side (higher scores), and it is not symmetric around a central peak.
• For the third histogram: The distribution of frequencies on either side of the peak is not symmetric; the right - hand side has a more extended tail - like structure compared to the left.

So the first histogram (let's assume it's option A if we consider the three as A, B, C) shows a shape that is approximately bell - shaped and symmetric, which is characteristic of a normal distribution.

Answer:

A (assuming the first histogram is option A, with the symmetric, bell - shaped distribution of scores)
