Question

Mr. Taylor wanted to study the effect of being absent on student test scores in math class. Mr. Taylor plotted the data he collected from his second period class on the graph below. Choose all that statements below that describe this scatterplot.



A scatter plot is shown with 30 data points showing a strong negative relationship. The x-values of the data points extend from 0 to 9, and the y-values of the data points extend from 100 to 0.



A.
There is an outlier at (3,40).

B.
There is a positive coorelation between days absent and test scores.

C.
The line of best fit for this scatter plot has a negative slope.

D.
As the number of days absent increases, the test scores decrease.

E.
As the number of day absent increases, the test score increase as well.

Answer 1

Correct choices: C and D.

- C is true: the line of best fit would have a negative slope because the scatterplot shows a strong negative relationship.
- D is true: as the number of days absent increases, test scores decrease (negative association).

A is not supported by the given description (no specific outlier at (3,40) is indicated). B and E are incorrect because they claim a positive relationship, which contradicts the stated negative relationship.
