14. Disk drives 2014, residuals again Here is a scatterplot of the residuals from the regression of the hard drive prices on their sizes from Exercise 6.

Residuals 300 100 -100 -300 0 05 10 15 20 Capacity 25

a) Are any assumptions or conditions violated? If so, which ones?

b) What would you recommend about this regression?
