    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
