Two brands of batteries are tested, and their voltage is compared. The data follow. Test the elaim that voltage of brand X is less than voltage of brand Y. Assume that both variables are normally distributed. use a 0.05 level of significance. Brand X Brand Y sample mean = 8.2 Sample mean= 8.4 O, = 0.3 n, = 27 oy = 0.1 ny = 30
