Question 936254
the manufacturer of an energy drink, ENERG, has a machine that fills bottles with 0.5 liter of ENERG. The amount of fluid in each bottle differs slightly and forms a normal distribution whose mean is 0.5 liter and whose standard deviation is 0.02 liter. what percent of the bottles contain less than 0.45 liter of ENERG?
---------
z(0.45) = (0.45-0.50)/0.02 = -0.05/0.02 = -2.5
------
P(x < 0.45) = P(z < -2.5) = normalcdf(-100,-2.5) = 0.006
