Question

A statistics teacher has 20 students in her class. Here is a graph showing the scores of the 20 students on a recent test.

A dotplot titled Graph A. A number line labeled test scores goes from 60 to 100. 64, 1; 75, 2; 80, 2; 85, 3; 87, 1; 88, 2; 90, 2; 91, 1; 92, 2; 95, 3; 96, 1; 98, 1.

The teacher selects a random sample of 5 students from the class. Here is a graph displaying the scores of the students she selected.

A dotplot titled Graph B. A number line labeled test scores goes from 85 to 97. 85, 1; 87, 1; 90, 1; 95, 1; 97, 1.

The teacher calculates the mean of this sample of 5 scores and plots it on a number line. She then repeats this process 100 times. Here are the results.

A dotplot titled Graph C. A number line labeled test scores goes from 86 to 97.

Which of the following gives the correct order of the graphs of the population distribution, distribution of a single sample, and an approximate sampling distribution, respectively?

A, B, C
A, C, B
C, B, A
B, A, C
