Performing the hapiro-Wilk normality test I get:
Shapiro-Wilk normality test data: residuals(lmMod) W = 0.94509, p-value = 0.02152
Am I correct if I interpret this as: Shapiro-Wilk normality test's H0 is that the population is normally distributed. Because the p-value is less than 0.05 this can be rejected as the chance that the population is normally distributed is too low. Short: The data is not normally distributed?
