20 a scatterplot is produced to compare the size of a school building to the number of students at that school who play an instrument. there are 12 data points, each representing a different school. the points are widely dispersed on the scatterplot without a pattern of grouping. which statement could be true? a..there is no relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster. b..as the size of a school building increases, the number of student musicians increases because the scatterplot has a cluster that increases from left to right. c..as the size of a school building increases, the number of student musicians decreases because the scatterplot has a cluster that decreases from left to right. d..the size of a school building is equal to the number of students who play an instrument because the scatterplot does not have a cluster.
