I made this normal probability plot from residuals. Would this graph show the data is not normal?
I made this residual plot in minitab. How do I describe the heteroscedacity of the data?
I created this regression model on minitab. How do I tell if it is significant, good and the percentage of variability that is explained by the graph?

- Okay thank you! I am still a bit confused on certain areas. So the first graph (the one with the S pattern) shows normality? And for the second graph, my prof. said that that homoscedacity residual graphs have no clear pattern. This graph looks like it has a pattern of getting bigger to smaller (like butterfly wings).
