Hi David,

I think Garp has given the wrong answer(even question , SSE and SEE has been mixed).Shouldnt the answer be 0.98.Now in this situation what should we take if the questions are wrong.
Plus,even if we take that to be SEE then I think SEE = (SSE/(n-3))^0.5 and not n-2.Point me if I am wrong.

Thanks
SIpani

You aren't wrong, nicely done!
Agreed, SEE is mislabled.
Agreed (n-2) is wrong. Actually should be (n-4) not (n-2) (yikes!)
How did you even get 0.98? (the question doesn't even really tell you the sample size??)
What to do if questions are wrong? I have no idea, hope the actual test questions are better..David

Hi David,

I took that as SSE,with that it came out to be 0.98.
Moreover they will be using Gujrati notation like SER or previous year notations.This gets really confusing at times.

Thanks
