Suppose that turnips in a storage bin have an average weight of 172 grams with an SD of 6 grams. 1. What is 169 grams in standard units? 2. Suppose that the histogram of the weights of the turnips in the storage bin follows the normal curve. About what percentage of the turnips weigh more than 169 grams but less than 178 grams? 3. Suppose that in a bin like this the largest 20% of the turnips can be packaged in special soup mixes and that the histogram of the weights of the turnips in the storage bin follows the normal curve. Find the 80th percentile for the turnip weights. 4. Suppose the smallest 20% also have a special market and you need to know the weight to use as the cut off for the smallest 20%. Find the 20th percentile for the turnip weights.
