My Question is if Series of Round trip times(RTT) is given.Then how can we find out The Smoothed RTT,The Deviation in RTT,The Time out interval at each value.

Please don't ask or expect us to do your homework for you. Your instructor gave you the assignment to do. There are loads of sites on the WEB for you to research.

If you can't answer questions or don't want to asnwer then what r you supposed to be doing here...

Yes and at the same time you are in these lessons to learn. What would you learn if we just told you the answer? And we are here to give advice, not to do people's homework.

If you can't answer questions or dont want to asnwer then what r you supposed to be doing here...

I'm here to help people make the most of their computing power by sharing my knowledge and experience. I volunteer my time which gives me the right to pick what questions I answer.

Most of here will not answer homework questions for the reasons both LT and I stated. On the other hand, if you do the work on your own and ask for confirmation that you did it correctly, that we may do. The point being that the assignment was given to YOU to do, not to have someone do for you.
