Roughly, 3.8+, 35+.
Now, to qualify those 'numbers'.
Stats are an important part of your application -- obviously. However, once you receive the secondary (which is given out based upon your primary application which includes the 'stats' AND your essay/ec's), the majority of the weight is placed on that. So don't shirk on it! Then they evaluate the secondary via 3-person committee and decide who to give interviews to.
Best of luck!
