Question

multiple choice 4 points select the most appropriate response. one normal curve has mean 23 and standard deviation 1, a second normal curve has mean 5 and standard deviation 10. the curve that represents data that is more dispersed, or spread out, is: the first normal curve the second normal curve they are equally spread out there is insufficient information to answer the question

Explanation:

Step1: Recall standard - deviation property

The standard deviation measures the spread of a normal distribution. A larger standard deviation means the data is more spread out.

Step2: Compare standard - deviations

The first normal curve has a standard deviation of 1 and the second has a standard deviation of 10. Since 10>1, the second normal curve is more dispersed.

Answer:

The second normal curve
