I totally forgot how to find a z-score. Please help and explain.
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 180 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 more than 196 oz.
Carl decides to answer the following questions about the population of vegetables from these sample statistics:
Carl calculates the z-score corresponding to the weight 196 oz. (to the nearest tenth) _______
Using the table below, Carl sees the area associated with this z-score is 0.____
Carl rounds this value to the nearest thousandth or 0.____
Now, Carl subtracts 0.50 - 0.____ = ____ %.
