A federal agency responsible for enforcing laws governing weights and measures routinely inspects package to determine whether the weight of the contents is at least as great as that advertised on the package. A random sample of 18 containers whose packing states that the contents weigh 8 ounces was drawn. The contents were weighted and the results follow.: sample mean=7.91, and sample standard deviation=0.085. Can we conclude at 1% significance level that on average the containers are mislabeled?
