As the value of robs gets smaller the error in prediction fr

As the value of r_obs gets smaller, the error in prediction from the linear regression line

a. gets larger

b. gets closer to the standard deviation of Y

c. gets closer to the standard deviation of X

d. both a and b

e. both a and c

Solution

As the value of r_obs gets smaller, the error in prediction from the linear regression line gets larger and closer to the standard deviation of Y So, answer is a and b.
