Ground Beef Weights Narrative
The meat department of a local supermarket packages ground beef using meat trays of two sizes: one designed to hold approximately 700 g of meat, and a larger one that holds approximately 1.4 kg. A random sample of 36 packages of the smaller meat trays produced weight measurements with an average of 715 g and a standard deviation of 90 g.
-Refer to Ground Beef Weights Narrative. Suppose that the quality control department of this supermarket chain intends that the amount of ground beef in the smaller trays should be 700 g on average. Should the confidence interval above concern the quality control department? Explain.
