# Concentric ellipses with TikZ

I am hoping to recreate the image you see below in tex (the original here was done in Word). After snooping around for some time, I see that this should be done using the Tikz package. However, I don't have any experience with this package and am trying to prepare this for a lecture relatively soon (poor planning on my part). Can anyone help recreate this image?

Thank you! Any and all help is much appreciated!

• Welcome to TeX.SX. Questions about how to draw specific graphics that just post an image of the desired result are really not reasonable questions to ask on the site. Please post a minimal compilable document showing that you've tried to produce the image and then people will be happy to help you with any specific problems you may have. See minimal working example (MWE) for what needs to go into such a document. – user31729 Mar 20 '15 at 18:01
