Mackenzie investigated the relationship between the number of hours studying and the test score for some of the students in her class. She constructed the scatterplot below.
A graph titled Hours Studying versus Test Score has Hours Studying on the x-axis, and test score on the y-axis. Points are at (1, 62), (2, 62), (2, 77), (3, 79), (4, 85), (5, 99).
Which statement is correct based on the scatterplot?
There is no relationship between hours studying and test score because the points do not form a straight line.
There is no relationship between hours studying and test score because there are multiple test scores for 2 hours studying.
