Q

What are the conditions and assumptions for the “Test for the Slope of the LSRL?”

A
  • The scatterplot shows a possible linear relationship.
  • For each value of X, the probability distribution of Y has the same standard deviation.
  • For any given X, the Y value is independent.
  • Y values are roughly normally distributed.
