Answer:
Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.
Step-by-step explanation:
Linear regression is a primary type of predictive analysis. It describes does a variable does a useful job. Which variable is significant.
Set of nine data pairs with correlation coefficient r = -0.4
Set of five data pairs with correlation coefficient r= 0.3
Set of four data pairs with correlation coefficient r= -0.8
Setoff six data pairs with correlation coefficient r = 0.6
A setoff four data pair with correlation coefficient r = -0.8 is the valid data set.
Because
r = -0.8
r2 = 0.64,
This is very close to 1 as compared to any other data pair.
Hence, Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.
