Weights of the vegetables in a field are normally distributed. From a sample Carl Cornfield determines the mean weight of a box of vegetables to be 172 oz. with a standard deviation of 8 oz. He wonders what percent of the vegetable boxes he has grouped for sale will have a weight less than 164 oz. Carl calculates the z-score corresponding to the weight 164 oz. Using the table (column .00), Carl sees the area associated with this z-score is 0. Carl rounds this value to the nearest hundredth or 0. Now, Carl subtracts 0.50 - 0.34 = 0. or %.
