(it isnt graded im just not sure how to enter it)

### Data Table The table below shows a set of data comparing the number of hours studied to test scores: | Hours Studied | Test Score | |---------------|------------| | 1 | 78 | | 0 | 75 | | 3 | 90 | | 1.5 | 89 | | 2.75 | 97 | | 1 | 85 | | 0.5 | 81 | | 2 | 80 | ### Explanation - **Hours Studied**: This row lists the number of hours each student studied for the test. - **Test Score**: This row provides the corresponding test scores for each amount of study time. ### Task Calculate the correlation coefficient to understand the relationship between hours studied and test scores. The correlation coefficient will indicate the strength and direction of this linear relationship. #### Question What is the correlation coefficient? [ ] Note: The correlation coefficient can range from -1 to 1, with values closer to 1 indicating a strong positive relationship, values closer to -1 indicating a strong negative relationship, and values around 0 indicating no relationship.
