Answer 1

There is a smaller standard deviation for the number of submitted scholarships for school A.

I just took the quiz.

Answer 2

To determine which statements are true, I'll proceed to examine them:

Statement 1: The range for the number of submited scholarships is larger for school A.

To determine the range of the scholarships aplications of both schools you have to watch the values in at the bottom of the graph, both schools A and B have scholarships that go from 9 to 15, so the range is equal for both schools.

This statement is False.

Statement 2: The range fro the number of submited scholarships is larger for school B.

The same as before, the range of scholarship aplications for both schools is the same, so this statement is False.

Statement 3: There is a smaller standard deviation for the number of submitted scholarships for school A.

The standard deviation is a measurement of dispersion, it is measure regarding the center of the distribution. The more disperse the data is, the further away the data is from its center.

The dotplot for school A shows a greater variability than the dotplot for school B.

This statement is False.

Statement 4: The standard deviation in the number of submited scholarships is the same for both classes.

This statement is also False.
