Are women less likely to be successful in engineering?

I am a high school student that would like to be an engineer and I am also doing a paper on females in the field of engineering. Your TEDTalk is one of my sources. I am wondering if you have any thoughts on the question, "Are females in the field of engineering less likely to be successful?" and if you have any other female engineer friends?
