A manufacturing company measures the weight of boxes before shipping them to the customers. Assume that the weights of boxes are normally distributed with mean 90 lbs and standard deviation 24 lbs. Find the probability that a randomly selected box will exceed 94 lbs.
--------------
z(94) = (94-90)/24 = 4/24 = 1/6
----
P(x > 94) = P(z > 1/6) = normalcdf(1/6,100) = 0.4338
