Question

Consider the following data generating process (dgp): yi = 10 + 2xi + ui , ui/x ∼ i.i.N(0, σ2 ) where observations for x are generated by a uniform distribution [0, 30]. (a) Write a R script that, using seed 123, generates a sample of 80 observations from the dgp above setting σ 2 = 144. (b) Run the script. Plot the 80 observations in a scatter plot without including the fitted line. Is the scatter plot as you expected? Comment. (c) Now, repeat the parts (a) and (b) setting σ 2 = 16. Compare the graphs and comment.
