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 ?
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....
