![]() ![]() Corn crops must be tested for aflatoxin, a poison whose concentration varies widely between and within crop yields. A grain processor has received eight crop yields, but the distribution of aflatoxin in parts per billion (PPB) must be assessed before they can be accepted. This example uses the file aflatoxin.sav . The data consist of 16 samples from each of the 8 crop yields. |
