Question 1191671
z=(x-mean)/sd
so z>(193/180)=1.072
that probability is 0.1418
-
This is z=-282/180 and z=18/180 for probability 0.4816
check with calculator 2ndVARS(700,1000,982,180)ENTER for 0.4812. The difference is that I rounded -282,180 and the calculator doesn't round until the end. Ask how much they want the z-value rounded to.
