Question 1085502: One normal curve has a mean of 20 and a standard deviation of 5. A second normal curve has a mean of 5 and a standard deviation of 20. The curve that is more dispersed, or spread out, is
the first normal curve.
the second normal curve.
both; they are equally spread out.
neither; by definition, a normal curve shows no spread.

The large the standard deviation, the wider the spread of the data.

the one with the greater standard deviation is wider, or more dispersed.
they're both normal distributions, which means that the mean and the mode and the median are the same point in the distribution curve.
if you're looking for a point that is three standard deviations above or below the mean, then the curve with the mean of 20 and a standard deviation of 5 will go from 5 to 35, while the curve with the mean of 5 and the standard deviation of 20 will go from -55 to 65, a much wider spread.
