I hv done both ug and pg in correspondence..preparinv for pgtrb...really ur videos are so much useful ..please mam..if possible start class in you tube for pgtrb...so many people are preparing..kindly consider this..
Mam we can apply the two tailed test for all types of problems ...or need to apply single tailed test mam.....if I apply two tail test in board exam means shall I get full mark mam
