# Question: Tell if each statement is true or false for a

Tell if each statement is true or false for a simple regression. If false, explain.

a. If the standard error is syx = 3,207, then a residual ei = 4,327 would be an outlier.

b. In a regression with n = 50, then a leverage statistic hi = .10 indicates unusual leverage.

c. A decimal change is often used to improve data conditioning.
