The Food and Drug Administration (FDA) is a U.S. government agency that regulates (you guessed it) food and drugs for consumer safety. One thing the FDA regulates is the allowable insect parts in various foods. You may be surprised to know that much of the processed food we eat contains insect parts. An example is flour. When wheat is ground into flour, insects that were in the wheat are ground up as well. The mean number of insect parts allowed in 100 grams (about 3 ounces) of wheat flour is 75. If the FDA finds more than this number, they conduct further tests to determine if the flour is too contaminated by insect parts to be fit for human consumption. The population standard deviation is 10. The FDA cannot afford to sample the entire shipment so they take a random sample of 37 bags of flour for evaluation and finds that they contain an average of 79 insect parts per 100 grams. Test to see if the entire shipment of wheat is not fit for human consumption. Test the claim using a 5%…
