For which data set is a linear regression most reasonable? a set of nine data pairs with a correlation coefficient r = –0.4
a set of five data pairs with a correlation coefficient r = 0.3
a set of four data pairs with a correlation coefficient r = –0.8
a set of six data pairs with a correlation coefficient r = 0.6

A set of four data pairs with a correlation coefficient r = –0.8

Step-by-step explanation:

-0.8²=.64
