Question 1189095
z(240)>(240-200/15 or +2.67
probability z> 2.67=0.0038
-
between 191 and 209 is the same way.
calculator 2ndVARS(191,209,200,15) and that will equal twice the probability of z=9/15 or -.6<z<0.6
=0.4515.
-
230 ml cups are two sd over or 0.02275 probability, so 22.75 or 23 cups would be expected to overflow
-
z(0.25)=-0.6745=(x-200)/15
-10.12=x-200
x=189.88 or 190 ml

Note: there is an error in the problem. The SD is 15 milliliters. All units are in ml.
