The following data sets can be modeled linearly. Data Set M: {(14,95),(9,85),(4,65),(6,80),(3,73 ),(12,107),(7,64),(12,86),(10,96),( 9,64),(1,44)} Data Set N: {(13,109),(9,85),(4,65),(6,80),(3,6 3),(12,107),(7,76),(11,100),(10,96) ,(8,85),(1,44)} Use technology to find the correlation coefficient of each data set.
Part A: Which data set has a better linear model?
Part B: How do you know this?

B: Data set M has a correlation coefficient that is closer to 1.
B: Data set M has a higher correlation coefficient.
A: Data set M has a better linear model.
B: Data set N has a correlation coefficient that is closer to 1.
B: Data set N has a lower correlation coefficient.
A: Data set N has a better linear model.
