Answer

Explanation:

Step1: Understand standard - deviation concept

The standard deviation measures the amount of variation or dispersion of a set of values. A lower standard deviation indicates that the data points tend to be closer to the mean, while a higher standard deviation indicates that the data points are more spread out from the mean.

Step2: Compare standard - deviations

We have the following standard - deviations: Mrs. Jones: 1.9 Mrs. Rijo: 1.4 Mr. Phan: 3.4 Mrs. Scott: 6.1 Since 1.4 (Mrs. Rijo's class standard - deviation) is the lowest among all the standard - deviations, the scores of Mrs. Rijo's class are the closest to the class mean.

Answer:

The scores of Mrs. Rijo's class are the closest to the class mean.
