mrs. jones
89
1.9
mrs. rijo
82
1.4
mr. phan

Standard deviation measures the closeness of a dataset to its mean.

The statement that is most likely true is (b) the scores from Mrs. Rijo's class are the closest to the class mean

The dataset is given as:

Class               Mean  Standard Deviation

Mrs. Jones      89            1.9

Mrs. Rijo          82            1.4

Mr. Phan         73              3.4
