Answer

Explanation:

Step1: Recall the property of standard deviation

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

Step2: Compare the standard deviations

Compare the standard deviations: (1.4<1.9<3.4<6.1). Mrs. Rijo's class has the smallest standard deviation ((1.4)).

Answer:
