You observe that the distribution of weights of individuals drawn from a random sample of the united states appears bimodal; there are peaks at 130 lbs. and 165 lbs. you were under the impression that weights follow a normal distribution. why do you think this distribution differs so much?

Because of the number of overweight and underweight people

Explanation:

The peaks appear because there are significant numbers of overweight and underweight people, compared with a relative small number of people with normal, average weight.

In today's society there are two extremes: the overweight and the underweight people, they make up the largest part of the population and this is why weight does not follow a normal distribution any longer, it concentrates in the peak measurements.
