Question

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they exercise in a week:

On a grid, Label Hours of Exercise on x axis and Test Scores on y axis. The title of the graph is Test Scores and Exercise. The scale on the x axis shows the numbers from 0 to 10 at increments of 1, and the scale on the y axis shows numbers from 0 to 100 at increments of 10. Dots are made at the ordered pairs 1.1, 12 and 1, 30 and 2.1, 21 and 2.5, 42 and 3.5, 30 and 3.5, 45 and 4, 55 and 5, 45 and 5.5, 60 and 5.5, 70 and 6.5, 40 and 7, 50 and 7.5, 80 and 8, 75, and 8.5, 60 and 9, 75. The ordered pair 9, 15 is circled and labeled as T. All the other points are put in an oval and labeled as P.

Part A: What is the group of points labeled P called? What is the point labeled T called? Give a possible reason for the presence of point T. (5 points)

Part B: Describe the association between students' test scores and the number of hours they exercise. (5 points)
pls explain both parts

Answer 1

Part A: The group of points labeled P are called a cluster while the point labeled T is called an outlier. The presence of point T could be because one student got too carried away with exercising and forgot to study for the test.

​Part B: For most of the students, as the number of hours they exercise increases, their test score increases too.

Explanation:
