Answer

Explanation:

Step1: Recall standard - deviation concept

Standard deviation measures the spread of data. A smaller standard deviation means data points are closer to the mean.

Step2: Compare standard deviations

We have standard deviations: 1.9 (Mrs. Jones), 1.4 (Mrs. Rijo), 3.4 (Mr. Phan), 6.1 (Mrs. Scott). Since 1.4 is the smallest among them, Mrs. Rijo's class has data points (test - scores) closest to the class mean.

Answer:

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