    help with original claim/null hypothesis:

    For homework, I have to find out if husbands outlive wives. I have the gathered data of 10 couples; the years wives have died and the husbands have died so far. So what would my original claim be considering this is a matched pairs problem using the T-Test method? Would it be μd=0 OR μd>0 ?

    Discard the data where both are still alive, label those couples where the wife died first h and those where the husband died first t, Now the null hypothesis is that p(h)=p(t)=1/2 (that is the process is equivalent to tossing a fair coin)

    do husbands outlive wives?

    ok, I had actually changed my data to 30 couples. So now I have made my original claim: μd>0. Since I am "assuming" right now for the project, that husbands outlive wives....
