Question

Select the correct answer.

If the weights of 1,000 adult men in a county are plotted on a histogram, which curve is most likely to fit the histogram?

A

a U-shaped curve, better known as a normal distribution

OB.

a star-shaped curve, better known as a normal distribution

C.

a bell-shaped curve, better known as a normal distribution

D.

a bell-shaped curve, known as an exponential distribution

Answer 1

C. a bell-shaped curve, better known as a normal distribution

Explanation:

We assume that 1000 adult men are selected at random in a county, their weights are measured and plotted on a histogram. In such a scenario the weight plot is expected to fit a normal distribution. The normal distribution is centered on the mean of the weights and helps determine the weight deviations from the mean. A normal distribution curve is shaped like a bell with the highest point corresponding to the mean weight.
