A researcher wants to show the mean from population 1 is less than the mean from population 2 in matched-pairs data. If the observation from sample 1 are Xi and the observations from sample 2 are Yi, and di, = Xi - Yi, then the null hypothesis is H0 : \mu d+= 0 and the alternative hypothesis is H1 : \mu d 0.A researcher wants to show the mean from population 1 is less than the mean from population 2 in matched-pairs data.
