So, I am doing the interval for regression. And I am making the assumption of the samples. I was given two data, after I enter the data into my calculator, I found that I don't know how to
make a scatter plot to show that the there should be no pattern in the residuals plot.
After that, I also need to check if the distribution of the residuals are normal.
I am confused, because I saw there are two graph (the solutions) on my books which can response to the assumptions above. I just need someone guide me to make these teo graph in TI-84. Thank you!!!
