In a bottling process, a manufacturer will lose money if the bottles contain either more or less than is claimed on the label. Suppose a quality manager for a steak sauce company is interested in testing whether the mean number of ounces of steak sauce per restaurant-size bottle differs from the labeled amount of 20 ounces. The manager samples nine bottles, measures their contents, and finds the sample mean is 19.7 ounces and the sample standard deviation is .3 ounces. Test the hypotheses at α = .05 using the critical value rule.
