Question

A scatterplot is produced to compare the number of hours that students study to their test scores. There are 25 data points, each representing a different student. The scatterplot shows a grouping of points rising from left to right. Which statement could be true?

a. There is no relationship between the number of hours that students study and their test scores because the scatterplot does not have a cluster.
b. As the number of hours of studying increases, test scores decrease because the scatterplot has a cluster that increases from left to right.
c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
d. The number of hours that students study is equal to the test scores because the scatterplot does not show a cluster.

Answer 1

your answer should be c

Answer 2

The scatter plot isn't showing up. Without seeing it, it's not possible to know for sure. However, the key phrase "grouping of points rising from left to right" seems to suggest that the answer is choice C. The more you study, the higher you're likely to score on the test. It's not a perfect relationship, but there's a strong positive correlation.
