The label on a bag of potato chips claims that there are 3mg of sodium per serving. Suppose an agency is going to test this claim. The agency will only pursue a case if the mean sodium per serving is to high. A sample of 576 bags produced a sample average of 3.700. The standard deviation of sodium per seriving is known to be 6. We want to know whether the new software changed the mean. 1. What is the...
