In the mouse and rat problem u mentioned that is a one sample test and later on u used the formula of two sample test...in your week 2 lec 9 also there are mistakes in little things..if u carefully watch d video u get to know...please before uploading check the videos to ensure correctness of all d contents..otherewise these very little mistakes can create confusions in the minds of students...
In lecture 17:09 ,we are testing one tailed test . Ho : muR =Mu_M Ha : Mu_R < Mu_M Calculated test statistics value is -6.89 table value for 0.05 l.o.s is 1.746 but for left side critical region we take it as - 1.746 Decision - we reject Ho if t cal < table value where t cal is -6.89 < -1.746 so we reject Ho
Brother Currently i'm doing that course from NPTEl So in his PPT it written like " If T calc is < t table we accept the Ho" Than here why we are rejecting it??
what is sp ? standard deviation or standard error? what p stands for in sp? I noticed in many places in other videos too you are using Standard error and standard deviation interchangably, and it makes me cofuse
14:30 what you said one sample t test ok But you use two sample t test😑😑😑 Kya notanki hai yar, km se km book to bata dete to yha in vidoe me dimag ni khapan pdta. Bkwaas sub hai ya ye teacher ya IIT aise hi padati hai kya pata please tell me somebody😑

Yes you are right
We can also use two tail test.

Bhai tu revision kar ek baar
14:30 what you said one sample t test ok
But you use two sample t test😑😑😑
