The test of the null hypothesis that ñ = 0 requires that the sample is independently and randomly selected from the population of interest (A), that the distribution of Y scores at any value of X is normal in the population (B), and that the variability of Y scores is the same at each value of X (C). Therefore, all of these assumptions must be met for the test of the null hypothesis to be valid.
