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), (3,63), (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?

Select one answer for Part A and one answer for Part B.

B: ​Data set M has a higher correlation coefficient.
B: ​Data set N has a lower correlation coefficient.
B: ​Data set M has a correlation coefficient that is closer to 1.
A: ​Data set M has a better linear model.
B: ​Data set N has a correlation coefficient that is closer to 1.
A: ​Data set N has a better linear model.
Is it the first A and last B?
