Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Refer attached Both are same .
please re-read the question carefully.
ok
it depends on the test that we are going to apply . If we do find ROC by formula we take an = eq1 and if we are doing ratio test for complete series then eq2 is correct .
but see in finding ROC you used eqn 2, please examine.
here I have used ratio test , not used ROC formula .
why are we using the ratio test to find the ROC?
we can use any . Here Ratio test is easier . That's why we used ratio test .
