It could be B but double check to be sure
Add the total of both groups and divide by the total number in each group
Group X = 535 / 18 = 29.72 mean
group Y = 500 / 18 = 27.78 mean
Group X has the higher mean
X is -1 . if you put the equation into form and do a two step equation you should end with -1
